Here's how I would start if I was you. 1. Check compression, the engine you have is the 720 engine. 150 compression is perfect, 130 marginal and at 120 it is done. There should be no more than a 10psi difference between cylinders 2. Replace ALL grey TEMPO fuel lines. They were not meant for today's ethanol and will produce a green goo that will clog the internal carb filters. 2. Rebuild carburetors with ONLY genuine mikuni rebuild kits, be sure to order new needle and seats as well. 3. Replace the oil filter and the small 3/32 oil injection lines from the oil pump to the engine. I would highly recommend keeping the oil injection system. Seadoos is the most reliable by far, many seadoo mechanics have never seen one fail and you will use much less oil. However if you are adamant on removing it be sure to keep the oil line running to the rotary valve, it needs oil or you will kill the engine. 4. Misilanious things.

If the trailer has sitting for a while you might want to repack (grease) the bearings in the wheel hubs.

Make sure you replace the fuel lines and rebuild the carbs (with genuine mikuni parts). The fuel lines from that era break down into green goo and plug the carb internal filters which will destroy your engine. I just rebuilt a 98 GSX Limited and trust me - those two things are ESSENTIAL. Also be sure to change the jet pump oil. Have fun, they’re great skis.

I’m in the middle of a 97 gtx rebuild this is my second jetski rebuild you’re going to have a blast once you get it running

Looks good from the outside gonna need some work but once it’s done it’s gonna be totally worth it

Never owned one, but looking forward to seeing your restoration. Keep your interesting projects coming!

I can't wait to see updates on this project!

It's a "Bombardier" - made in Quebec, Canada.

Just found this in my suggested! I have a 95 seadoo jet boat. Definitely do a wear ring (it’s in the jet pump). 2 strokes should be easy to fire up just make sure you clean or rebuild the carbs, new fuel lines, do a wear ring, and check the impeller why you are in there. If the impeller has any chunks or bends replace that too. Other than that you should be all set. You can PM me anytime if you have questions. I have a little over 5 years experience working on this kind of stuff! Look forward to the next video!

Hi from Dublin ireland, great channel, really enjoy your projects, looking forward to seeing this jet ski come back to life 👍🏼

Pressure washing the ski with some soft music in the background is all I needed

Nice to have a helper to give you some different camera angles, and that pressure washer worked a small miracle!

Two strokes dont have oil filters and theres no oil in the engine to change, the best gas stabilizers are only good for about a year. Good luck.

Amazing score. Love to see you bring it back.

Luckyyyyy

I have 2 I’m fully rebuilding. I just did my seat yesterday it looked just like yours. I duct taped the entire seat and bought the blacktip seat covers from amazon and now they look great.

Hey so first advice is remove spark plugs and put some Atf fluid into the cylinders to lube up the walls and piston. That jetski has been sitting for a very long time and the last thing you want is to mess up the cylinder walls. Second advice, do not spend any money on cosmetics until you know that the jetski runs. Get a new battery or jumper box to see if it turns over. But never ever disconnect the battery or any power source from the jetski while is is running. It can damage the electricals. When you actually get the jetski running make sure you hook up the flush kit and only run water when jetski is running and shut off the water before shutting off jetski. And do not run jetski outside of actual body of water because it can mess up seals and other things on the pump shaft. And one last thing, when you do finally get it out into the water to test and the jetski accelerates awesome but feels like it aint moving much than at that point your going to have to check your wear ring that goes in the jetpump.

This is so fun to see since I recently bought a 2002 Seadoo GTX DI (very similar). i hope you get it going. It's a lot of fun!

Cool dude with cool content! Love it keep up the great work!

This should be a learning curve for you, I’ve had my first ski for 6 years (Yamaha go1200r), and it’s needed a few things over the years. Now it need another top end rebuild which I’ve never done, but they’re quite simple to work on (2 strokes). As you mentioned, you want to rebuild the carbs. Clean the fuel system and change the lines, if the fuel cock is stiff at all just changing. I’m not sure about these, but on yamahas it’s recommend switching to premix and getting rid of the oil system, as it’s more to go wrong. And again on the Yamahas, we usually get rid of the chokes and fit fuel squirters for cold start. Also worth checking clearances on the pump, between the prop and the wear ring. If it’s worn you can replace bearings and wear ring easily.

Wow that thing cleaned up nice!!!

Love all your videos. Thanks for sharing. You're just a young cat so you probably won't get the reference but you look just like John Philbin when he was young and played as "Turtle" in the movie North Shore. He was cool like you.

Careful with barkeepers friend, there’s an abrasive in it that tears the clear coat up. Will cause your paint to really start having problems

Nice to see that you have great project. Enjoy it

Can't wait to see this build. I just bought a C10 and a go kart for the son that I am going to build.

I own this exact ski but an 03 model. We’ve had it for 3 years and it’s a great reliable ski. We pull tubes and it tops out at about 44mph with me on it.

Put a few drops of that two-stroke oil down in each cylinder... When you try to turn it over the first time leave the spark plugs out...

Legit, the nicest guy on YT.

Step #1: Put oil in the cylinders and let soak. Step #1a: Clean fuel tank and fill with 50:1 premix to supplement the oil injection untill it has a chance to prime. Step #2: Pull the carbs and rebuild them with OEM Mikuni parts. Step #3: Replace the oil injection hoses and ALL fuel lines Step #4: Pull the pump and check the bearings and the carbon seal Step #5: Assuming the engine runs reassemble and load test on the trailer prior to taking it for a ride and check for water leaks!!

The music and power washing is so satisfying

that was awesome

Should be an interesting build looking forward to it

My parents have the exact same ski. Infact I just got done working on it yesterday. The 717 motor is a 2 stroke so there's no oil to change. There's a tank that you fill with oil and it mixes on its own. The uper exhaust manifold bolts are notorious for backing out. Also there are basically freeze plugs on the exhaust manifold that are designed to crack if water freezes in the cooling veins. They eventually crack just because of the extreme heating and cooling cycles that happen when you operate the ski. Most people just tig weld them back together which is what we did. The fuel lines go bad every few years and it causes the motor to bawg down. It does that because the fuel lines actually colapse. If you run the ski while its still hooked to the trailer you can see it happen. Plugs need to be changed every year because they foul very easy. It's because they never reach temperatures obove 145 degrees and the plugs are really designed to be operated at 190 degrees. There's a wear ring in the jet that may need to be replaced. It's not terribly difficult for someone who is mechanically inclined. If the reverse doesnt work its probably just needs adjusted. Reverse doesn't actually engage a gear. Basically a cover pushes down over the jet and re-directs water toward the front on the ski so it moves backwards. Its operated by cables and rods. Its probably a missing or lose screw on the back of the ski near the jet. The motor is pretty reliable although not real strong. The ski will top out at around 45mph. If you got it for free you did good. If you decide it's too much get with me and I'd probably buy it from you

Good find! Should get it running before making it look better. Mechanical work should be done first before spending money and time on cosmetic work. Best of luck on your new project

Love these videos

I have rebuilt a lot of marine engines . We are in Kissimmee . First thing I would do is pull plugs and soak for a few days with marvel mystery oil and then turn motor over by hand slowly because if there is rust or a stuck ring it could break . If motor is locked from setting take marvel oil and acetone and mix half and half and soak for a week and it will break it loose . Don’t worry about compression if it is a little low right now crank it let it get hot and move the rings and the compression will change trust me .

Awesome score . Waiting to see it run . Mike Espo .

I am telling you man that this stuff called purple power works amazing in that stuff. You can find it at dollar general

5:36 I could watch this all day:-)

Good stuff brother. Looking forward to seeing this joker run and the cost of getting it up. Used to live down there and there are a ton of these laying around. Always wondered if they are worth fixing.

To simplify, it’s pronounced “bomb ba deer” 😊 Great work!

Nice ski

I thought there was a 14 year old sandwich in that tupperware at 9:45 🤢🤮

Your videos make stuff like this look so easy. Then I try it and mess up😂

My brother bought a 98 gti 720 and wasn't running right . My 2 brothers changed the fuel lines cleaned the water separator and took the fuel tank or gas tank in America out and found gunge in the bottom of it cleaned it out reinstalled it fresh petrol but we premixed our fuel with 2 stroke before we put into the tank , cleaned the carbs , new spark plugs new oil in the pump . And running well now . Time patients plenty of tlc doing it right before you start and put it into the water . But when you do put it into the water lift up the seats and check your carbon ring isn't leaking . Enjoy

Looks like you're missing a storage compartment under the rear part of the seat. Should be easy to find. That's a nice ski. 85hp. Handles really well I used to have one.

The parts alone can be more expensive than the ski when rebuilt.

I have a SeaDoo 2003 gtx and water is going inside the motor to the oil any thoughts what it could be? I had to flush the oil and put new oil back in multiple times to get rid of the water fast.

Yo you are doing really good keep it up

Remember to check the oils if it has A automatic oiler on it to. If not mix in the tank then. Accept the case oil.

bom-bard-yea Love the channel, subscribed!

I'm a jet ski mechanic and I've never seen a ski that's been sitting for that long clean up that well that's crazy.

DAMN! What’s up girl?

Cool bro!

The one that you definitely want to do before you put it in the water is change that boot for the outdrive the propulsion unit sitting that long I’ll guarantee you it will leak

The seats you can most likely find them on eBay or amazon, now the paint for the top of the jetski you can use Normal paint that’s fine but for the hull you can use normal paint but it’s better that you use gel coat paint cause that is able to handle the rocks and waves and not crack, and lastly the steering and reverse the reverse handle is a cable and most likely rotted and broke so that’s not that bad of a fix and the steering is also a cable to check if that’s bad you grab the pump that’s on the back end of the ski and move it left and right and the steering column should move with the pump! 👌🏽

I’m going to replace the oil it’s a two stroke lol

Carb rebuild and gas line replacement for certain. Put a ton of fogging oil in the spark plug hole now and let it soak in for a while before you turn it over. On older engines so people put in auto transmission fluid to break up the rust that might be in side.

You can paint the plastic covers with car paint. Control cables get seized when they are not lubed with cable lube not WD-40. Once you replacement buy a can and use it. It has a rubber cover and allows you to push the fluid all they way to the end. Steering is also some cable or linkage assembly which you can free up and keep lubed. Use marine grease when you can get it for this application as it will not sling off. Key to happy jet ski use is wash and flush after use then spray with WD-40 all the metal parts of the impeller and jet outflow. I bet if you spend less than 500 bucks you will have a really nice machine! Looking for the first start video.

Pronounced Boom bar dee a - company is from Quebec in Canada - man that cleaned up nice. I think you have a project.

I have a 91 Yamaha. Always had problems starting until I completely rebuilt the carb and cleaned it with an ultrasonic cleaner. Now starts every time

this summer just use it as it is, in-home depo is the foam canisters fill the gaps on your seat with the foam then just try to give it a shape or find a seat cover, do the rebuilding in winter this summer you need some coca-cola Pepsi Fanta burgers gas money to have it in a good shape you need around 300-to 400 dollars

Totally thought that was a burrito in that container at first. Thought shit that’s gonna be bad don’t open it.

Make sure to swap the new tires onto the original rims on the jetski trailer. The ones you have will rust out eventually

I have 2 of the same year and model..... They are the VW's of the jet ski world. They dont go super fast. Just dependable.

Pretty cool my 1st was a seadoo xp that haf a blown motor, then i bought a 2001 gti and then a 2002 gti to go with it...

The irony is that there are lots of KZfaq videos on this that he should watch like everyone else.

How did you manage to find an oil filter for the 2 stroke 😂

I’ve rebuilt several including paint, stickers and replacing the non-skid. I’ve used automotive paint and as long as you scuff it and prep it, it will look brand new. I documented it on my Facebook account so let me know if you have any questions. It’s quite the undertaking but worth it in the end. It was my first jet ski as well and it had been sitting for about 15 years.

Maybe pour about 3-4 oz Transmission fluid in ea cylinder and let it sit for a day or two. Save you a headache when turn motor over no need to break some ribgs, also think about doing away with the oil injection and mixing your oil and gas together. Better performance. Great find wish you all the best with the new toy. Drive it and gave fun be sure to grease the rear seal at the tail shaft and all the zerk fittings. Take your time start at one end and move your way down. Check and double check your work.

You can get new seat covers from blacktip jet sports as well as new traction mats you’ll want to replace fuel lines if there grey they have a thing that makes them deteriorate on the inside and it will build up green goo in the fuel lines if your on Facebook there’s a group called seadoo two stroke owners and we all help each other out with mechanical help and where to get parts get OEM parts as much as possible aftermarket stuff seems to cause more problems and it’s not worth it in the long run great ski man!

That acid they use for concrete works on rust and calcium too.

Great video's!!!.....Quick question, if you don't mind......Where do you shop for parts, decals, mats, cleaners, etc. online? I am currently reupholstering / remodeling my 2003 Yamaha Wave Runner 1200 GT and would greatly appreciate any assistance with the matter...Thank you!! Extra Info : It was left out in the sun. So mainly have to reupholster the seat, replace all decals & mirrors, pressure wash & clean the white fiberglass footing area. Otherwise the engine is in mint condition with less than 200 hours on it.

Can't give any advice, but great content for the channel.

I have 2003 and 2006 gtx seadoos. They are a lot of fun! That motor in yours looks like a 2 stroke. I don't think that it would have crankcase oil nor oil filter. My GTX's both have the rotax 4tec engine. Enjoy!

You can get a replacement cover from sbt. That’s a lot of cracking on the foam. Better off getting new foam. You can also get mats through sbt. You’ll want to fill in the holes from the plastic rivets seadoo uses. Just fill them up with some silicone or better yet fiberglass resin

Slap some fat wheels on it and make it the worlds first rally-doo! 😂😂😂

Its a 2 stroke no need for oil change oil filter just clean the carbs or rebuilt chek the carbon seal the reverse if its not working its gona be the reverse cable succes im looking foward fo the next vid

fucking amazing video this is the definition of taking care of your toys 😂

Who in God's name let's a Ski get *THAT BAD*

Me: Jeez that pressure washer is big. How many PSI is it? Ultimate Rebuilds: Yes!

Get it wrapped!

nice. one mans ex is another mans new boo. looks good man

I'd definitely of had some more to say if you were just starting on this. Personally the older barbardier models are just not that great but with some engine mods like a turbo and performance upgrades including the impeller. I've seen guys get these to be 75mph skis one thing I would say if you keep doing boats learn about gel coats. Also what two cycle engines are and how to make them last. Good job tho

Bombardier is the company that makes them. im sure if you look around on there websites youll find a replacement seat for it.

Bomb. Bard e eh🇨🇦

Thats a pretty nice jetski, i would like to see you fixing and improving it, maybe a purple would look good! Brazilian fan here👍

if you want to ever make hull cleanup easy go to the dollar store and get the cheap toilet bowl cleaner. do it away from any grass. will make that hull bright white. this is how we clean hulls coming off muddy lakes.

You should go with yellow because I think it would look perfect with that JetSki

Definitely clean out the carb before first start there is prob bad gas and gunk in it and it could lean out and blow

on and off hull cleaner will take those stains off in seconds . I just used it on my new ski that sat in the water. It is insane

The yellows stain on the hull the best product to use is Mulratic acid

CLR or LimeAway rust remover will probably work on those stains.

I have the same one bought it 2 years ago. They put a brand new engine in it so I bought it! I’m having a problem with it. Anyway we can chat to possibly see what the problem could be?

If you haven't herd of cataclean.& STP motor oil treatment& Marvel myserty oil you might want to check those products out. Along with some gum out octane booster to put in your ethanol free fuel. One more thing you half you use that cataclean in those jet skis in 3 ounces of fuel on 1/4 tank of fuel. Then fill it back then try it out again for A rip. Then let it cool back down then go riding it.

What should you do to it put a first gen turbo hyabussa engine in it

Yeah that's a 2 stroke, so no oil filter or oil to change. Fuel stabilizer won't work for more than about a year, siphon all the fuel and oil out, rebuild carbs, fresh gas and 2 stroke oil, but before you do ANYTHING else make sure the engine isn't seized and compression is good. Probably need a new battery. I don't recommend trying to turn the engine over from the starter, get a pipe wrench on the drive shift and make sure it spins freely and pull the spark plugs to make sure there isn't any water in the cylinders.

the seat looks like bread lol

3M rubbing compound will take that stain off with very little rubbing. It will even shine it rather than the comet cleaner dulling it.

Don't paint yet try wet sanding a small area of the gelcoat like you are color sanding paint min 400 and polish. If it won't polish up don't try to re-gelcoat it will be a lot of work and tricky. Prime and paint with marine coating like AwlGrip. Dupont Imron works well also.
