A Seadoo Story - Episode 3 - The Flywheel That Flies And A Disappearing Allen Wrench!

Latest installment of the 1993 / 1994 Sea-doo spx & xp project. In this video I remove the flywheels and switch the stator from one engine to another because the two types were different. I also install the new engine into the xp.

[@nickdanaluk566]

This episode is a masterpiece. You never seem to get frustrated whereas many others would run away from these projects.

[@halethewhale]

Your videos are so useful I’ve picked up some great tips so thanks for that, it’s also nice to see a genuine normal guy using normal tools that most of us have and it’s not some fancy shop with crazy over priced machinery

[@evanjohnmo]

That was soooooooooooo lucky to find that tool in the head. Imagine if it fell into the case.

[@mrfrog3350]

In my 35+years of working on and building cars,trucks,boats and aircraft, I have NEVER seen anyone loose a tool in an assembled engine.I guess we just do things differently here in Detroit.Glad you pulled the head and found your offshore compliant allen wrench.

[@SIXPACFISH]

You have to use what you have, not what you wish you had. Good to see someone using good common sense in a youturd video. Common sense is not very common any more.

[@youtubeguy3544]

SIXPACFISH Common sense isn’t spelling KZbin wrong

[@SIXPACFISH]

If they stopped acting like turds people would stop calling them that. They get people hooked into making this their job, then cut their pay by 2/3's so they can no longer make a living. All because some use this as an outlet to spread the truth.

[@grahamcox8385]

Youturd is right, pootube is a good description of them too, this awesome dude posted a 10 minute video and shitty pootube managed to cram 8 ads into the video,if that doesn't show how crap the admins at Youturd are then what does, then they have the nerve to ask me to pay for the privilege of having the ads removed, the only privilege I will give them is the honour of being told to fuck off quickly 😂🤣😂🤣😂👍

[@ImRichRu]

For anyone watching this 8 years later, you would have been so much better off just doing a top end job on the lower compression engine, imo. Cheaper and easier to do. That said, huge props for doing it the crazy way.

[@mrroadrage6804]

i didn't think anyone ever found 10mm spanners I thought they just lose them

[@jenniesgarage]

Thank you, it's fun to work on the ol' boat!

[@jenniesgarage]

That's true. They might smoke and use a little more fuel, but definitely easy to work on and maintain!

[@SirFloofy001]

The seadoo demands a tool sacrifice! You can not remove a tool from the seadoo without the seadoo taking another!

[@OkFixer]

There are two gizmos on the bottom of the hull inside. 15:26 They are called scuppers. This is the reason your boat is not dry inside when you take it to the lake. They (remember this is a Canadian machine) do the opposite of what they were meant to do. They put water IN your boat, and not remove it. Remove them and plug the holes in the rear. Also, I see you have one of those cheesy Bombardier bilge pumps. Notice they put it level with the carbs. This is to insure once the scuppers have done their job, the engine will suck a giant lung of water and bend a rod, before the pump comes on. Discard this worthless piece and put a proper bilge pump on the very bottom , with a fused switch in your glove box. Also check your pulse line to your fuel pump. If its original it was made from pixie foreskins, and will fall apart causing your engine to suck air. It will run really good for about 10 seconds, then melt together if this leaks. I realize you got it for a song, but there is a reason for that. I would sell that to the next sucker at the lake next year. If you want to avoid these and many other French foibles, by an Asian machine.

[@sloppyengineering]

Lol nice

[@olliecrow3547]

I can't believe the Allen wrench was in there! What a way to conclude a video. Wow!

[@jenniesgarage]

Thanks, glad you enjoy the videos!

[@bondvagabond42]

You can put the flywheel nut back on loose to prevent the flywheel from popping off all the way while pulling it. Great videos.

[@havoc010101]

This was another great how-to video. Thank goodness you didn't try to start the motor with the allen key inside the motor. Dodged a bullet there!! Keep the content coming!

[@zdgSRghE]

This series is all the fun of working on a jetski, but it doesnt destroy your hands like really working on a jetski lol

[@G56AG]

You mentioned something about safety and the grinder, so let me relate one experience. I went out for dinner with friends one evening, during the evening one got a call, another friend had been working on something with a grinder with the shield removed, just like yours. While grinding on something the disk shattered and a chunk of it entered his stomach, he bled out before the ambulance got there, the news of his untimely death kind of ruined the evening. Every time I use a grinder I make sure that safety shield is firmly attached.

[@jenniesgarage]

I know, things could've been much worse! It was frustrating, but luckily no harm done!

[@victormaggrah1251]

That's exactly where I thunk that Allen wrench went to! Lol. Glad you found it.

[@dylansmith7850]

Victor MAGGRAH yeah

[@Gmtail]

Next time just stick a rag in the exhaust port. Quicker than the trimmer line, which the hardest part was probably wrapping it all back up. Lol.

[@r.jjetskivids5810]

Lift with ya back bud!.lol. Cheers for showing step by step, doing a project like This myself but on a kawi js300

[@jenniesgarage]

Thanks, it's getting closer and closer!

[@spratsprat3266]

Can I donate to buy you an impact wrench

[@lukasaey]

he has one now

[@craigmonteforte1478]

SBT is. The company that sells completely rebuilt. Engines. They are in Florida an have been doing watercraft and snowmobiles for years. Excellent score ! You bought a old machine with a new engine that's a good score they SBT does use. All original. Factory parts on their rebuilds and at one time they had a great warranty. And service department i used their engines on two occasions with Perfect. Results btw pulling the jet pump and impeller is not as. Difficult as the shop manuals portray it to be. In the books and factory literature they. Were very adiment About needing SeaDoo pullers that were ridiculously priced from Bombardier. I made my own using some angle iron, all thread and a nut. Tacked in place it worked great and didn't cost me the 90 bucks the SeaDoo one was you are right on track. About customizing tools. For the tight quarters. The engines are in over time i wound up with a strange assortment of 10mm box wrenches and sockets As i remember that being one of the most common. Sizes another trick a guy that builds race. Engines. Taught me was to always use CopperGasket. Spray on. The head gaskets his claim. Was that was the only. Thing to prevent the head gaskets. From leaking under the high compression and heat he was a Kawasaki Jet Ski. Specialist But i used. That on all the machines i had over the years a interesting. Fact. Was on the Kawasaki motors if the gasket leaked it would allow exhaust gases into the waterjackets and. The motors would not cool properly and overheat ! As you probably know by now the cooling water is " pumped through the motors by a tube in the jet pump thru the motor and out into the exhaust. System to help muffle the noise and keep the pipes cool too on the alignment of the engine and shaft. I always. Just simply put the shims. Back where i found them and never had any issues ? Ive had at least 6. Engines in and out of Watercraft over the years including a new SBT motor. And a rebuilt Kawasaki. Stand up motor which in over 10 years of ownership proved to be the most reliable. Motor of. All the machines. We had also the least powerful too as that was only A 650 dual carb setup and i think the one you are working on. Is a a 700 dual carb, the SeaDoo motors were always the more powerful in the power band. For some reason. Their motor and machines were. Always faster than many others i own a old SeaDoo that has had. Many performanc parts. Put on. The machine is. A 1990. And has all the. Original graphics and seat on it But that. Machine is very quick out of the hole and has pissed offmany other riders on bigger machines At top speed those guys would blow me away but not out of the starting spot it. Basically has upgraded impeller. And a Coffman. Exhaust Plus a bored Mikuni carb Not. Really. Anything high tech. It was one of my first machines ever and i went overboard on the performance. Stuff. Ive always told my freinds it. Isn't. Worth the costs for what you get out of the parts. But i did it for. Fun and entertainment plus it was a learning experience If. I was ever to reall build a true sleeper i would do a complete engine swap on a machine that looks old and crappy but stick a 1200 motor under the seat another. Small peice of advice. On the SeaDoos is something i heard you say. A little about. But want to emphasize greatly. Is cranking the starters. A great deal. They do overheat and fry very easily. And are expensive plus a pain in the backside to replace ! I spent. A full Memorial weekend at the beach one year in the dark. Replacing one because the whole family was. Asking if they can use one of the jetskis on the trailer Of course. I. Kept thinking to myself. How hard can it be to. Replace. A stupid little starter ? Ive. Done. Harder things. Than that It was a bitch finding one on Memorial weekend. When everyone is closed plus working in the 100 degree heat out in the sun With kids asking is. It done yet?

[@joshsalmons1]

It honestly drove me crazy that you didnt clean the engine/engine bay, before you put that engine in there! My ocd was absolutely killing me!

[@luisrodz7511]

Who can dislike this videos?? I really enjoy them.

[@DIYDanCars]

Nice video! You will want to pay carefully attention to the jetting in the carbs with that aftermarket APE pipe and flame arrestors. Good luck!

[@zakkiller223]

probably why the original engine blew. it ran too lean. melted the pistons, well one and caused detonation or ringland failure on the second

[@davidhook261]

I choose to believe that it is a newly remanufactured engine and that way when I drive around I will feel like I'm going faster! Funny stuff! :-) love it!

[@stephenspann27]

"Do you even lift....engines" lol.

[@wallpaperman9051]

That’s crazy how that makeshift tool fell in the spark plug hole. I kept my eye on them cause I didn’t want to see anything fall in their and ruin the piston and cylinder. Unbelievable how that just happened to fall in there.

[@darrellcoy]

Found a SnapOn 1\4 in drive ratchet with an 8 mil socket in my truck after detailing the engine bay.

[@lucymandrell]

Some of the best KZbin video ever

[@devonforsberg5725]

Imma be honest I’ve never laughed more watching a informative engine sort of video 😂

[@meatloaf666999]

"Dat asteroid." I got a good laugh from that one.

[@Bradwick1]

ROTAX Resurrection...The musical...lol Tool retrieving magnets look to be essential in Sea Doo world.

[@jenniesgarage]

Thanks so much for the compliment, I'm glad you liked the video!

[@vince3198]

Have you thought about doing another ski restoration video or maybe a snowmobile one??? Idk if you have snow where you live, but I watch your videos from beginning to end ALL of the time haha.

[@DvisionScorpio]

Lmao I realized at this moment that these Videos are already 4 Years old, you wouldn't notice it! Nice quality! Suddenly like the actual Videos

[@zarins92]

Hey! I know this is an old video of yours, but it takes time to go through all of them :D As for the small wrenches - drill a hole in one end and loop a string through it, that way if you drop it, you'll have one end attached to it for your convenience. Great videos. Greetings from North-East Europe!

[@jimmygrant3212]

The seadoo with the good hull and bad engine is modified. The cover for the flywheel being silver means it came off a 720cc engine. The reason the engine is bad is because if it misses while running it also won’t get the right amount of oil and burn up the motor as you can see.

[@forresttaylor6849]

I knew it. It was my first thought. Engine locked up? Found the Allen wrench.

[@timetable620]

My dad had a v10 cargo van and the ford v10s are known for spitting out spark plugs. Well at the time we were changing one sitting in a gas station parking lot. He hit the button on the back of the ratchet on something and it released the socket and extension right down the spark plug hole. Luckily we could get one of them magnet extensions down and pulled it out.

[@mwilliamshs]

Time Table how does a spark plug socket which fit the largest diameter of the spark plug, fall into the spark plug hole, which is necessarily smaller?

[@timetable620]

mwilliamshs I am sure sorry I didn’t specify that it wasn’t the spark plug socket. See when it spit the spark plug it also broke the little plastic tab that holds the coil pack in. So when removing the 10mm bolt he dropped that socket down the hole. Not the spark plug socket

[@yamahafan7330]

If you come across that situation where you could loose the Allen key (or tool), just use a rag underneath so it catches it if you drop it.

[@MATHEWTHOUIN]

awwwwww i see the problem '' dish soap'' thats why it popped off when you were driving it that day :) lol

[@MisterZealot]

for future small metal things going in tight places, I'd recomend a "stick with a magnet" I have done some work on planes where the space is limited at best, so.. for a screw falling in the tight spots for example (wich could be catastrophic if left there), nothing better than that. o/c we used a "professional tool" but it's nono more than a glorified old telescopic radio antena with a magnet at the end. xD

[@87meow]

Yes whevnever I drop something I find it 16 miles up the road 2 months later. I feel your frustration .Love the vids

[@gsallen9588]

Pretty amazing how your engine was hexed. For the future I'd recommend taking a sharpie to the end of the trimmer line so you can affirm no length loss; or use some nice, finely-braided, limp rope to fill the jug after the piston is down only an inch or so (to avoid clipping via the flow ports). Purchases or yard-sale finds I'd recommend: Telescoping or goose-neck retrieval magnet and an impact wrench (such as HF 1/2" electric, often on coupon for $39.99 or less). I was surprised you didn't put on carbs before installing the engine (or maybe you snarfed a granola bar off camera). I just came upon your vids via the 90 > 125 swap, the non-generating Generhack, etc. Quite the amusingly-singular narration, videography, humor and wife-play. Enjoyably unpredictable and satisfying repair outcomes. Bravo! I look forward to more such original docu-dramas. Gracias! (P.S. Sans major tools that most hoard in triplicate, you provide great encouragement to the budget DIYers, while also revealing the most essential gadget: confident willful persistence. No-turning-back is the paramount hack. Did you feel lucky on the stator coil diameter accommodating the flywheel, or was that pre-assuaged by measurement?)

[@ethanenglish6146]

you should make a dirt bike trailer out of one of the jet ski trailers

[@jdef1]

That looks like some seriously powerful cavitation on that piston to me. Don’t know how it would happen, but it looks the same...

[@christophersanchez2698]

Definitely had carburetor issues! To the extent that thing was running super Lean. Lean Conditions also mean not enough lubrication.

[@zegentertainment1024]

I’m sitting here wanting to pull my hair out.. but at the same time I watched a friend cram a completely different model motor on a body of another snowmobile, not only make it all work 100%, but finish it all in 6 hours.

[@Steinerrides]

Well it did need carb work. that engine must have been running super lean. Ring got so hot it crushed the piston. Probably still ran ok until that happened

[@LeObsidianCraft]

Matthew Stein either too lean or a bad pump for the water cooling

[@Steinerrides]

Yeah that's true, but the ring crushing the piston leads me to believe it was too lean. the ring usually won't crush a piston if the waterpump is bad because the whole cylinder heats up and expands to and allows the ring to expand as well. if the cylinder is being cooled properly, and its running too lean, the heat causes the ring to expand, but not the cylinder, leading to a crushed piston. It could have been a combination of the two as well i suppose

[@Steinerrides]

Also you generally don't get melted pistons unless it's leaned out because you get a hotter flame. If your water pump is bad, you shouldn't have higher combustion temperatures to the point where is starts melting stuff.

[@stephencresswell4760]

Good catch on that Alan key. What a fluke.

[@joegardiner4220]

Be interesting to see if the cylinder with the messed up carbs was still within tolerance. The lack of compression was probably due to the lack of sealing rather than cylinder wear, maybe a honing and you could of salvaged them for spares ?

[@jlucasound]

OMG! Never have I seen or heard of that! Well, no harm, except for the extra labor, and you are up two custom allens and a 10mm. Nice one , too! (No, you didn't find the 10mm in the cylinder). ;-) I am so glad it did not mar the combustion chamber. Many would have rammed it and destroyed everything in that jug. No Good. Those chambers DO look nice.

[@lnknprkfn]

the stubby allen wrench was probably dropped in the exhaust port since you left such a large gap when you went to use the allen wrench.. not the spark plug hole.

[@GuyDarby]

A free good quality 10 mm ... that's wort the work , on it's own ! Can never have enough 10 mm ..

[@BlairWilliams]

If you call SBT in florida and give them that number on the side they will tell you when it was built.

[@jenniesgarage]

Thanks for the tip, it would be nice to know the history.

[@SirFloofy001]

so THATS where all the 10MM wrenches disappear to!

[@gkmerkel]

Thank god you fought the urge to start it and you decided to crank it over by hand. You would have done all that hard work for nothing!!! Can't wait to see it running:)

[@jlucasound]

@ 5:05 It was either run on straight gas or some one ran it dry. It looks like no water. No oil would have been worse. Just a guess. Depends, though, on how long it was run, in either condition. It got very hot. My guess is the water pump failed and they decided to "limp" back to the launch ramp. Engine is garbage. BTW I am loving this! I think you will come out ahead. The useless 1.5 hour drive sucks. This hull has potential. I know, 7 years ago. I just discovered you guys last year!! ;-)

[@birdwing98]

21:32 A smart guy like you would tape a tether to that tiny allen wrench.

[@davidhook261]

Do you know what the mathematical probability of you dropping an L-shaped allen wrench down a spark plug hole? That is absolutely amazing that that happened! Man I love your chill attitude! I would have been probably throw in tools! :-) good good stuff!

[@jojo2664]

👍👍👍 positive and calm👍👍👍👍

[@LSDdreams808]

Man yout videos are super interesting gear work you did

[@jenniesgarage]

Thank you, good to hear you enjoyed the project!

[@FunnyHacks]

4:50 that engine probably made some very bad noises while making those marks! On the first piston, I wondered if there was something physically present in the cylinder. (Note that you definitely have more experience with these than i do.)

[@MrShrabber]

welcome to SBT Where nothing is the same lol or for that matter functionality

[@jenniesgarage]

I was thinking about making a "convertible" where I could quickly attach and detach a platform. Then I could use it for a boat, dirtbike or general utility. Maybe a winter project :)

[@cwatson42785]

Thank God you turned that by hand before starting it up with that wrench in there. How the hell did it fall in through the spark plug hole? I almost fail to believe that lol

[@J3n555]

The bad engine had severe pre-detonation. Maybe from running low grade octane fuel?

[@jeffreywaltiere4830]

The first cylinder looks dry Second Son looks really good

[@jayhiz3514]

I did that to a engine before, few little shots of nitrous in a 2 stroke will sure cook a piston

[@jenniesgarage]

It was a crazy thing, but it made things interesting!

[@cameraman1234567890]

657 and 657 different year engine swap. Sounds like something Id do. I just Did a 2003 GTI 720 single carb swap with my 1996 SPX which is normally twin carbed. The carb was brand new, so thats another reason why I went with it. That and better fuel mileage lol.

[@elitistseeker1258]

I gambled on a jet ski this season and it didn't work out so well it needed a carb clean once I did that it ran for a little while and then blew right up

[@spitfireap77]

Please hit that engine with a little degreaser!! Even the Dollar Tree stuff works pretty well.

[@tasmedic]

I hope you realize how lucky you were that your cut down allen key blocked that piston from moving. Imagine the effect of starting the engine, had it been free to move inside the cylinder. Moral: always put some oily rag in the spark plug holes, or leave the plugs in there loosely. Same applies to intake and exhaust manifold ports.

[@brandon2076]

The bad engine DEFINITELY had a pre-ignition issue...what caused it is a mystery.

[@yz4me60]

WOW!!!! i was honest to god thinking "he should have the plugs in the spark plug holes just to keep dirt from getting down in the cylinders"...and uhh o yea...keep allen wrenches out!!!

[@jake-rx9rs]

Never say eye ballin the shaft lmfao

[@david65711]

They put automotive plugs in the bad engine they burn too hot to close to the piston and it may have broke off and beat up that other piston

[@sailorbychoice1]

4:43 looks like something got sucked into the intake and got into the cylinder, I had a wingnut get sucked into a Cat 3208 once, looked a lot like that when we got it torn down.

[@bullenharben9905]

If you ever repair the knackered engine, maybe whack it in a go cart or buggy or something. It'll fly!

[@mafia631]

"This nut is.. Difficult.. to remove!" hahaha

[@farmingfishingfamilyontari2814]

It's like using a bulldozer to fix a wristwatch. I do not have this kind of luck.

[@ryantoomey611]

That pitting on the piston is likely due to not using higher-octane fuel, or using the wrong 2-stroke oil.

[@cohall46]

You have way more patience than I do when it comes to dealing with adversity. You custom make an allen wrench, you lose it, and then turn around and make another one. Bravo! Do you suppose that when the jet ski motor unit was put together the exhaust manifold was connected and then the whole unit was dropped into the jet ski?

[@raguhmuffin]

Awesome vid, brb checking for my missing wrench in head. I think it fell into the exhaust and not into the spark plug hole, seems more realistic that way. Anyone else think he talks like wranglerstar?

[@somerandomguy3868]

Lucky you are, and in more ways than one, wonderful wife, and you thought too turn the engine over by hand and then thought too remove the head, good job all the way around

[@sheawilliams8246]

My back hurt when he picked up that engine

[@charlesrose3303]

U fixed tht like a boss bro

[@ITzMonMotorSports]

Nice

[@ryanhays4504]

Oil injectors are known to go out witch could be catastrophic

[@davidhook261]

Absolutely love your channel! Keep the videos coming! What state do you live in? I have for jet skis I'm excited to get working on! :-) if you're in Florida, we should have a jet ski party and talk about blown up parts Etc! Love your story about an asteroid hitting your piston and causing a mass extinction event an old dinosaurs living around it! Good stuff! :-)

[@jenniesgarage]

Thanks!

[@andthesunsets]

Lol the hex tool..

[@robmckennie4203]

It looks like you got the model with the self removing flywheel!

[@raven4k998]

Remember kids if you drop a tool in your jetski and cannot find it maybe in the engine so be careful to check like he did before you try to start it up as it could kill your engine if theres a tool in the piston when you try to turn the engine over murphy's law can be evil sometimes

[@irgski]

Maybe you could have measured the various stator resistances to see what the wire colors should have been to transfer to the other engine?

[@rhpham2]

Nice work, glad its all put together. Cant wait to see it running=)

[@mickyjb2003]

Nice video, what did surprise me was how dirty the crank cases were but you didn't clean them when the engine was out. Also other parts that were really dirty hou seem to just them back with know concern. Did you clean them later or did I miss something?
