Answered a lot of my questions. Great video !

I have the last of the 2 stroke Yamaha 25s bought new in 2006, still have it, had zero issues! I run it on my honwave 3.8m inflatable.

That's a great engine. I purchased mine in 2018 for my 11 ft Whaler short shaft with electric start and steering wheel. I get 30 mph top speed with me (205 lbs) and gear in the boat.

great video! best of luck with your guide service!

Honest review. I think you nailed it.

Excellent! I just had mine out for the first time, I wasn’t concerned with the weep hole strength but I also noticed she shook a lot and the handle vibrates at idol but like you say any throttle at all and it’s gone, nice and smooth. Glad it’s normal. It ran flawlessly and it’s got some torque, the swivel tension feature came in handy. I’m happy.

Extremely helpful video. Many thanks.....all the way from London !

Great video brother. You did a great job with it. I have the identical same engine. I wish I had the auto tilt as well.

You sir are a Super Hero for this video. Much Blessing to you.

Great review 👏

Thanks for your honest review and the sights of the superb waterway on the front of your property! What happens when the river swells? What a smooth motor! I would love to have it in my Boston Whaler Sport 11!

Way to go Capt Eric. It's been great watching your growth. Was that a truck you were driving at the landing? 👍

The reason it vibrates is because it doesn’t have a counter weight to balance the pistons. Other small 2 cylinder motors have them to balance them. This is how Yamaha lowered the weight on the new lightweight 25 hp. I got that straight form Yamaha when I bought mine.

Good video I have an f25 on a Lowe roughneck 1860 runs 23 mph loaded Idid install the electric start ,it was an easy install , and it sure makes it alot nicer but the electric star kits have really increased I only paid 330.00 dollars for mine last year. I really think these motors should last a along time .Congrats on Captain s license hope to get mine soon. I am going to get one of those cmc trim plates when I find a used one because they have really increased in price also.

I have the same motor (20” shaft with electric start). Replaced an old 2 stroke Merc on a 15 ft Mirrocraft Stryker. After two seasons here in Wisconsin, I have no regrets. Starts in any weather, quiet, and sips gas. The vibration at idle does shake everything in the boat but it’s a small price to pay for the bullet proof reliability. My boat is heavy but it will still push 22mph with 2 people and gear. I paid $3,800 in 2019.

Very well done complete video.

I paid $383X out the door for a 2020 model in July of 2020. I got the same model as you but with electric start. It included a 3 gallon tank and fuel line plus dealer “setup” which was simply fill with oil and run it to make sure it was pumping water and then oil level recheck.

DUDE AWESOME VIDEO 🤙🤙🤙IM LOOKING AT A 40HP 4 STROKE FOR MY 14' BAYLINET... JUST THE REVIEW you gave of your motor REALLY HELPED ME OUT ALOT 👍👍👍WHATS THE NAME OF THAT LAUNCH RAMP? THATS A NICE 1 LANE RAMP... ✌✌✌

Great video and review. It would be great if you did a video on the electrical start upgrade installation. Is it costly to upgrade on the F25 in $?

Thanks Eric..I enjoyed that!!

Good video!👍

Awesome thanks buddy I was wondering weather or not to get the PTT 🤙😎👍

They're excellent engines. I have a 2 stroke 25 on one boat and a f25 on my other boat, both excellent, absolutely zero complaints out of either one...it's kinda cool having two of the same horse power engines, one being a 2 stroke and other being a 4 stroke ...I can do direct A to B comparisons in the differences.

Cool video I have purchased 1 with the electric start I’ve not used it yet! Is it hard to fit an electric trim kit?

Great video

I’ve watched every video you’ve done on your F25. Great work. Suggestion for another video: how did you determine the trim pin position for your boat considering sometimes you’re alone and sometimes you guide?

Great videos Eric! Very informative. I notice that you have a Runleader tach on your F25. Can you tell me what firing pattern you have it set to? I'm trying to set up my tach as well. Thanks.

I wish you put out more videos. You have the only good videos for the Yamaha f25

Hello, when you do you static flush are you getting water coming out of the lower unit bolts? I can see a small hole next to the bolt but not sure if that’s normal?

thanks for posting this have been looking at this engine for my boat was wondering if i really needed the electric start power tilt trim i had the features on bigger boat use to own that had forward controls i have a 25 hp tohatsu 2 stroke atm manual start and manual tilt tiller steer looking at upgrading to a four stroke efi model way go also

You mention you would go to a stainless prop, what one are you thinking about getting and what pitch? Would you do a review on it if you get one? I got the same motor and contemplating going to a ss prop too.

This is a good motor, i have the 9,8 Tohatsu 2 cylinder 209 ccm no and 150 hours, start in a lake, out in salt and back a channel in shallow tilting. Before i have this 71 kg Tohatsu 3 sylindered 25 and that was a good one, didnt change impeller until it started go bad and it lasted 12 years 1100 hours before boat stolen and crashed.Impeller change after 8 years..Ihave one yamaha 8 one year and also a ok engine. But no recently Tohatsu came out with a 500 ccm 3 sylyndred 25 the same weight as this yamha 25,. Next time if in the new engine purchase, i definately go for the 3 sylindered.But all are exellent engines. Al the best from Norway and have good boating trips=)

Does not having power trim help reduce damage to motor if you do hit a log? I would think power trim would lock the motor down while in forward? I am asking because I am getting ready to purchase this motor in the next day or two. I can choose between the bare bones or the one with electric start and tilt assist. I will be using the boat in really sketchy water with lots of logs (and gators). Price is not a concern. Damage to the prop and shaft certainly are.

Thank you good stuff

When you had this motor, did it have a small squeal? At idle or slightly in gear. Goes away at higher RPM

Great video and great engine! Just a few questions, do you what's the top speed with your configuration? And also, would you recommend it over a two-stroke engine, and why? By the way, you said that the power stroke happens every two strokes (180° phase between the two cilinders): that's usually what happens in 2-cylinder engines, but in the F25 case I read on the Yamaha website that the two cylinders fire simultaneously so the engine actually acts like a 1-cylinder one! (This might also be why it vibrates consistently when idling, obviously they chose to let it smoother when cruising)

I have the same motor but electric start on a j14. It’s been 2 years and I’m hooked. 29 with the wind in my face.

I bought a portable home generator years ago and I wish now that I would have paid extra for electric start. At the time the savings seemed important. It's gone the other way as well, where I bought extras on things that I learned later were not necessary. Great video.

Is it easy to chage the fuel filter? you just screw it out and put in new filter?

I've got almost the same setup with a yamaha 25hp and the CMC 30 and the 25 mounting bracket is actually the same size as the CMC mounting plate, leaving no good spot to bolt them together. Did you figure out a way to bolt the motor to the CMC?

Why not tohatsu? Their engined are lighter...any tips? Thanks!

I have an idea about the "weak stream" from the telltale i have and older '71 merc 110 9.8 hp it doesn't have a thermostat and even at idle the stream is very forceful because there is no thermostat to slow down the flow of water. In my new 2020 Merc there is a thermostat and at idle the stream is much weaker untill the engine gets nice and hot then theres a lot more water shooting out the telltale and the water is warm instead of cold. Im no mechanic but i belive the thermostat opens at a specific temp allowing more water to flow into the engine to cool it down. Whereas older engines without T-stat has full water flow all the time

could you tell me the type/part number of the after market power trim unit you got please... Great review video as well

my 2005 Tohatsu 9.8 vibrates less with slight throttle as well. It has electric start but i prefer to use the pull string. id imagine your motor is probably harder to pull start though. What power tilt in that? does it also work like a jackplate?

Hi, this is perhaps a silly question but where on the motor do you connect your battery charging cables to? I have the same model and just can't find the 12V power supply connector. Many thanks, G.S.

Hi, Can u tell me everything that is needed for adding the power trim? Where can I order it?

Have you ever had HP issues with yours? I’ve been trouble shooting some fuel starvation (at least I think) with mine. It’s been super frustrating

What model was the 14’ Jon boat you first put it on? Also, would you consider going down in hp to 20 or 15 to get more features like power tilt and electric start? Thanks

I have that same setup im installing a cmc pt 35 soon i was curious to were your cavitation plate on your motor is to the bottom of the boat it says 1”-3” high do you think yours is at a good height thanks

Nice engine buddy 👍👍👍...

I have this motor with factory electric trim and start. Wondering if anyone else has my problem the power trim won’t work above 3/4 throttle, hydraulic noise like it’s under too much load like when putting motor on motor support for transport. My cavitation plate is 25mm below hull plane so don’t think I am too far off height. Motor is on a f14 Frewza (4.4 meter alloy pontoon boat)

IS THERE ANY PLACE YOU CAN ORDER ONE ? THER IS NOT A SINGLE BOAT SHOP IN COLORADO THAT HANDLES YAMAHA !

Hello, what about high vibration on trolling mode? After F15 the vibration on hadle is to high!!!

Where can I find the power tilt kit? I have a 2023 25hp.

Hello. It is correct for water to come out of the idle hole?

Does anyone know why this OB leaks a bit of gas after use when its stored on its back? Its a Yamaha approved position, resting on the two "feet", tiller up. Assuming theres some sort of fuel collector on the return that leaks out a vent line?

Not sure if you answered this question already.... here goes: does adding electric start to this model give you the ability to charge the start battery?

How do u fix over flow of gas?? Like what's broken ?

Can you do another 3-4 year review? Pro/con, looking to upgrade this year and getting rid of my 2 stroke.

70 miles on a tank. Is that nautical miles or land miles? I just bought the F20 with electric start and I'm just exploring the range potential.

E um elelente motor como faz pra ver presso

Can this motor help bring back home a 30 ton 70ft cruiser?

Did you ever add the electric start?

Please tel me whot and whare you got the motor tilt

I believe water got into gas tank. Bogged down shut off a mile from ramp. Would love a tip. Same motor. The carb looks different and that scares me.

You and your yamaha got a weak stream, HA! Mercury! mercury! mercury! Just bustin balls lol. Congratulations on the captains license by the way. Pretty cool.

How much would you sell the 9.9 yamaha?

yamaha are durable engines but unfortunately on the smaller ones like 20 hp and 25 hp they only have two cylinders and vibrate quite a lot. Since you don't have power trim, it also becomes very heavily steered when you pull as you can't adjust the engine up and you have to struggle to keep the tilt all the time as it pulls on the engine. Replaced my yamaha with a new Mercury 30 hp and what a difference in engine. It runs so incredibly smoothly as it has three cylinders and the tiller has so many adjustments and you have the power trim original and what a low draft in that engine and very easy to control at all revs and you don't have to wrestle with the tiller at higher speeds. But above all no vibrations, it is very irritating as it vibrates constantly in the Yamaha.

but heavy engine 60kg or more ?

What’s your top speed

Your choice on cmc tilt is better than OEM, it is serviceable and cheaper. Prop, the stainless won't flex on 25hp motors, and are heavier to spin but for the same pitch they are thinner more durable, so it's a wash. Yammie props are best, don't waste $ on aftermarket, I tried them. The tiller handle vibration can be fixed, tighten the gland but behind the sleeve one turn to tighten handle then remove tiller handle add a washer inside on the spring when you remove the handle.

I'm GUESSING the fuel economy Must be pretty good on it If your boat is fairly Light ???

nice video man when I get my 50 I'll sell you my mercury 30

How fast does it push your boat?

No Ida then eh?

Most of the cooling water comes out of the exhaust. The weep hole is just to confirm that the pump is at least operational.

4200 out the door here in Washington state

Woohoo! I'm "like" #200!

Lol “I’ve hit an alligator or two”. You don’t hear that every day.

What is the wot rpm. Prop size and pitch . Boat weight. 4 stroke engines wot should be at or very near the top of the rpm range of the motor. Thanks

I use a 12 volt motorcycle battery to start Yamaha 25f. It cut down on the weight in my boat.

Sorry, but I actually DID just order this online. Straight from Overtons. Came right to my door like any other item you’d order online.

Capitan license what ta hell what you have go to school to get a capital license. I think that's stupit

No compression release for starting? Not buying trim and tilt was a major screw up. Now u spent more having to buy after market plus resale is not as good. People prefer oem features not bolt on. Maybe u put your water pump impeller on backwards. Rookie.

Keep the aluminum prop dude..it's a cheap insurance policy stainless if you hit something big you can fuk it up bad!!! I seen it I happen more then once I got the suzuki 25 2021 just as good...
