That Mysterious Canister is almost certainly a Racor fuel seperator being used as a Catch-Can for the AIRBOX DRAIN. 2-Stroke Detroits have Drains coming off the Firedeck/airbox inside the block, to drain off the oil splashed out of the cylinder liner ports. On a Motor Vehicle, they are allowed to just drip down on the ground, except in California. You Check the Fill Level in the Catch-Can every few days, and Drain it into a small can or bottle, and just Pour It Back Into the Engine. Or, if you do Oil Analysis, very EASY to get your Samples...Its' Purpose is to keep oil out of your Bilges. Hey, while you have the engine out, Check the Seals on the Emergency Shut-Off Trapdoor in the top of the Blower, or maybe the air intake box. It looks like a Trapdoor that can fall down over the Blower opening and Shut Off Air from coming in. This is a VERY IMPORTANT Safety Piece on ALL 2-stroke Detroits, its to prevent or stop an Engine Runaway. The seal around the edge of the door MUST be in Good Condition, Air-Tight, for it to Work. Also Check the metal Mating surface, make sure it is Clean and Flat, for a Good Seal. I didn't see it in the vid, check and make sure some Dumb-ass has not Removed it. This is the ONLY WAY to shut down a Runaway Two-Stroke Detroit! If you can't put a Load on the engine big enough to Stall It, the ONLY Other way to shut it down is to Shut Off it's AIR. If it runs away, it WILL Suck the oil out of the oilpan, and Run on THAT til it Blows.

"Oh look, it's an Oyster!?" and "I am definitely getting too old for this." 8 minutes in and 2 awesome quotes! Keep up the great work!

Thanks for taking us along Stu. I was getting flashbacks to when I was mechanic watching this vid. Your making great progress

Mad max called he wants his crane back

I'm not into boats but glad I found this rebuild, seen the last few and they where good. Thanks for the Upload.

I'm only really interested in sailboats, but I accidentally tripped across your videos and now watch them with breakfast. There's something comfy about a dry sarcastic Aussie fixing boats.

All that hard prep work...and it looks like the engine came out easy. That was a good plan! Well done...

I have enjoyed your videos for about a month now, you're not afraid to work and have a good set of skills. I like your desire to tackle jobs that you have not done before and learn as you go , best wishes to you and keep up your great work !

Finally up to date (just watched everything back to back from your first video).After 45 years at sea on "steel" boats you are doing a sterling job.

Awesome Stu, look forward to the next episode, great progress.

Woohoo! 24 minutes of Dangar Stu goodness!

That crane was quite the contraption! I’m loving this series. All the best.

A man with a big heart and the power to tackle anything. Murphy law “if it is going to drop or fall it will to the most difficult place” and it did. Once the engine is out you can get it back....keep it up your doing good. Your also showing the rest of us the hiccups and many of work rounds that are needed to move any job forward. It never goes as the book says....you show the truth.....amacf

This is the best way to rebuild a boat. Gut it, clean it, fix it and reinstall everything. Thumbs up.

You are brave, I really admire the patience and the documentation of the whole process

Your work ethic and diagnostic approach are second to NONE. Excellent work, excellent video production and highly educational narrative. No wonder so many viewers are riveted!

Another great instalment thanks Stu. And the Landy still adding a touch of class on the hardstand....

enjoying this journey you're on Stu - nice work mate.

I like to watch people work and you add the element of fun. There is a lot you can do to sort out the engine room and improve access.

Awesome, so many interesting things to work on. Good luck with your repairs!

Great work!!! I like to see every corner of the engine, good plane changes!!!

This is adictive. Thanks for taking the time to share!

I was amazed when I saw you use the camera to "see"how things were when you took it apart. I use that method on all new projects. The work you are doing on the 4-71 is bringing back some old memories of the 6-71's I once worked on. These engines had over speed trips that shut the engine down if it got out of hand. They were generator sets.

Good job! Reminds me why I gave up on inboard engines. Working on an outboard is so much easier to get around it.

Thanks for posting! Even though I will never do this It’s so cool to see how you think about things and brainstorm! I always learn things from your videos!

Keep it up friend stay motivated! This is very intriguing and can't wait for each and every vid to drop

Super work on your videos.One strategy I use when taking stuff apart like this is to get a big pack of small multiple color zip ties and just tag both sides of whatever I'm taking apart with the same color ties.Pretty durable and they will hold up thru pretty rough service like cleaning or getting moved around.Stay after it man.

awesome work there, we had a 6-71 Detroit diesel back in the middle 1960's lots of power …

a pack of different coloured insulation tape or zip ties are awesome to keep track of where things go and what connects to what, great stuff Stu.

I run my own business, but even still I cannot just simply do do whatever I want whenever I want, other people will think I'm being lazy. So today I've hidden in my room, locked the door, and pretended I'm writing letters when In fact I'm watching you take an engine out of a boat........Love it

That crane looks familiar. Isn't that the one Noah used to load the elephants onto the ark? 😂

Wow this is turning out to be a bigger project than I thought, but that's how boat work goes. Good luck to you

I have no intention of ever owning a boat but I could watch you all day. You should be on TV!!

I'm enjoying your series. I have a love for all working boats. Yours will be awesome when complete. Tc, Mike

That engine is so happy you came along lol

Great bit of progress. Thanks for the video.

Good video, can't wait to see it all going back together.

The Green Machine is going to feel neglected. Another banger of a video.

Nice progress ! Really enjoying this series !

Ahhhhhh you can’t leave us hanging like that !! Great video sir

Love this series, keep it up man

Love this boat. Has lots of posibilities. Great video. Subscribed.

Great site I love every episode.keep them coming.

Really loving these videos, my son and I enjoy watching, about time you employed a full production team. -My dad

Excellent progress Stu

That was a big job, but now you're really getting to know the boat, and that will pay big rewards in the future. Also, Rob is the man.

Awesome progress Stu! It sounded like it was raining for parts of the video? Thats dedication! Great job keep up the great work and thank you for sharing so much of the process :)

This channel has rapidly become my favourite channel. Great work mate...

I've subscribed to your channel. I love boats and I love good restorations like the one you're doing on your boat.

Thank you for another great video! Watching you work on your boat makes me wish we had warm/nice weather here in Upstate New York (USA) all year so I can work on my current boat restore project. But, due to the frigid cold and snow......guess I'll have to wait a few more months. See ya in the next one.

Great to see more🤘🤘oh and 1st 😁.. you really are great at giving step by step info .. only if I could apprentice under you

Hello from Detroit Stu. Pulling the engine was a good call...gonna make your life a lot easier. She's a little dirty and tired, but she'll be a beast for towing. The hull really has some nice lines, gonna look great when you get her painted. Keep plugging along bud. Thanks for posting

The Boats coming along well, look forward to next weeks video. Thumbs up from NY👍👍👍

These videos are addicting. Great video 👍🏾

Man! Good Lord that blower intake was dirty!! Love this series brother, absolutely fascinating!!

Excellent video Stu! I felt for you getting those bolts undone - I have several times told people myself that half of working on engines is putting yourself in uncomfortable positions while undoing intake manifold bolts 1/16th of a turn at a time with coolant dripping on your face. But the reward in the end is addictive!

Very interesting project. Thanks from America!!

I enjoy your video's, keep up the good work mate

Thanks again Stu for producing awesome vids

I hope the tide doesn't get to the motor when it comes back in? Great series Stu! Love the video work, and the work work.

Stu ,that job has got to be a lot more work than you anticipated!!!! Holy shit!

This series is fantastic.

Love it the old spanner down the bilges we have all been there once or twice 🤣 I’m playing catch up on your videos Stu keep up the good work pal 👌🏾

Loving this project Stu

pulled 2 8v71 out of a 53ft Hatteras. Made rail road tracks to stern. Pulled off with boom truck. 6000 lbs. Nice work Thanks.

this is addictive viewing, great to watch,ty

Hi Stu greetings from Wasaga Beach Ontario Canada Love your Videos and glad to see you have a bottle of Sailor Jerry's for your down time.

Great stuff !...look at you go.....You certainly are determined to get it done. Waiting for the next Vid

As an ex trawlerman I am really enjoying your progress with this little vessel, I would defo fit deplex fuel filters mate they can save your life in bad weather if you have to do a quick change over, if you don't need a deck wash then just pull that system out, it would give you better access in that tiny engine room. Loving the bottle of rum in the wheelhouse top man, keep up the fantastic work.

Your a very patient OZ,hope it will be worthwhile on completion good luck

Since you have problems with the through hull valves and there's no strainer plus you're already welding. I'd recommend looking into doing whats called a sea chest. It's basically one through hull that you can hook multiple fittings too. They are much safer, easier to service in or out of the water etc and its cheap to make.

Good work on getting the engine out! Those cable tie mounts one trick i do with any boats / cars / switchboards i use them on is to cut the sticky backing pad off the back and araldite them it works amazing and stay there forever u just need to tape them in place until araldite sets. I would almost be tempted to rewire using tinned wire could even use numbered control wire and build yourself a wiring schedule to keep on board. Awesome work mate wish i had of seen your channel before i pulled my 90s model 225evinrude off my boat and rebuild the whole boat im sure i could have got it started for a few fishing trips!

Amazing that so many of the engine's serviceable parts couldn't be reached without dismantling almost everything. Hope you got the ziplocs!

Love it.......your a mechanical genius and I enjoy this video.😀

I can imagine you may feel at times "should I have taken on this project on" but at the end of the day I reckon you've got a great little boat there that I know you'll get a lot a pleasure with.

this work pays off,all sort of problems show them selves and get sorted out

You have the patience of a saint Stu😁👍

great work, I see Sailor Jerry there helping out

I love that crane. That looks like it would be great for setting concrete blocks.

I was worried when in your videos I didn't see a beer can anywhere. Jerry got you covered. Beware of one thing turning into another . You have quite a few cans of worms opened now . Doing a fantastic job so far .

hi stu i know it must be costing you a lot for all the things that need doing but slowly slowly wins the race she is goin to look the bees knees when you finished there are a lot of people watching and we are all cheering you on as much as you dont think the people might not want to watch this bit well let me tell you we do we are all routing for you all the best stu

That is a really big project you got going there stu..

Sailor Jerry's on the helm!! Yeehaw! My favorite!

One of the best time savers for a job like that is about 6-8” of telephone cable which has thousand of different color bundles then you start with white on terminal and white on wire then blue and blue and so on and so on Great to keep in the tool box Find someone who works for the phone co and get a foot of it cut it in half youll be set for a life time

Great points about documenting where things go before disassembly. 👍 Haven't found an oyster in my motor before. I was hoping a pearl would roll out for you. 😊 We have a monstrous forklift here at my job that was beautiful when it plucked my sterndrive V8 motor/trans out of my cruiser...twice. Heavy lifting equipment with a healthy motor and hydraulics with good seals is a beautiful thing indeed.

What a great video keep up the good work.

Big job pulling that motor, but you tackled it like a boss Stu! It will be much easier to work below without the Detroit in your way.

Hello Dangar, is it welding episode? I was waiting for so long? Cheers good man and thanks for AV material

Of all the boat build/makeover projects on here yours looks like the one that will require the most patients by the time you are done.

Great training video series, feel like I am doing the work myself !! LOL Thx, Peace

The crane looks like a Hamilton crane. Lot of them in new zealand. Watched one operate today. Cheers mate

Mate.....Sailor Jerry Spied Rum......one of our Favourite......Lucky you going to need a few bottles beginning-during-and the end of this little exercise 😊.....🍹

Well done Mate, that's a Big Job , few would tackle themselfs ! Inspirational :) Oyster in the intake :) , making great leaps and bounds , keep up the good work !!!

Congrats on getting the engine out...and your spanner back :)

Great episode, you are doing a detailed and thorough job. ✅👍🏻 Your channel is going to smash it and well done mate New follower ✅👍🏻

Excellent work am following avidly. Doing the same was a dream of mine. Hope nothing goes wrong with the refurb.

When I was in the Army I learned a trick to see things that are in tight spaces. We used the camera on our cell phones to take pictures or videos to see things in hard to reach places like your mystery belt.

Great video

Well that was very interesting Stu. Even though the engine itself is simple to get out was surprised by all the hoses going to it. The Oyster shell in the line was a laugh😂. Lucky you had a friend with a portable crane. Allot of work for you but it will be well worth it in the long run. If you take on another one like this down the road you can hire people to do it. It would be like flipping houses. Haha😁 Oh also now the heavy motor is out the weight on the stands may have changed so you better recheck them. Relax and bit before diving back into it buddy. Tim

"Im just going to put these screws someplace stupid so I'll be sure and lose them". Perfect line.
