2015 Yamaha FX Cruiser SVHO Jet Ski Engine Repair Part 4 of 5

- Les, the Canadian Swamp King, ran into a bit of trouble with his 2015 Yamaha SVHO FX Cruiser personal watercraft jetski when it suddenly quit on him. So naturally we volunteered to take a look at his engine and see if we can fix it for him, as it is our winter break, after all.
This video is Part 4 of the series. Here we split the crankcase cover and determine the extent of the damage, and possibly the cause of the water ingestion.

I actually love these videos. Not enough watercraft projects on UA-cam like this. Keep um coming!
This is the best learning video I ever watched . Lerned so much already . Keep up great work
Thanks, Jajco.
Thank you for confirming which way the coupler and cover bolt are threaded.
Love the repair videos. If only they were a touch longer. Keep up the good work, already keen to see the next video!!!!
Greatest repair video ever .
This is like having a Yamaha repair manual.
Thank you guys ! ❤❤
Thanks, Steve!!
All I can say is thanks for making a great video.
I'm learning so much guys from all yours video. Thank you !!!
You keep saying "we" the whole time. I only see one guy doing all the work..... Great videos!
Someone has to keep the beer cold while he's pulling the engines apart.
Good job and nice filming. I'm an hobby mechanic and have restored PWC engines looking much worse than that. It must be much cheaper to repair compare to replacing the engine. Especially if you volunteer with you labour . Good luck and looking forward to future videos.
Thanks! These type of comments help to keep us motivated.
Making wonderful videos. Keep up the good work.

If you have any removal and install videos that would awesome.
We don't have the removal video (it was taken out by someone else), but we'll make the installation video, if the owner wants to fix it. Stay tuned!
u guys deserve way more subs!
Another great video. Thanks.
Can someone answer this question, I have a Stator issue with a FX SVHO unit and am not necessarily planning on removing the engine to get it out
Can you remove the stator housing with the bearing and seal out of the transfer shaft ? Will it slide over the shaft to remove the housing or is it an absolute must to remove the transfer shaft ?
So what was the problem? That was a emulsion (mix of oil and water) you won't get that from water getting into the engine whilst it wan not running. You will only get it whilst it was numbing. Have you checked who serviced last ? I would suggest the engine sucked in the water.
You're right. We don't think it got in from towing, any more. Still a mystery as to how the water got in. But Les (the owner) died recently, so the project is on hold.
Good video
Turns out it was a cracked cylinder head. Two other Yamahas in our group had the same problem.
3ftDeep Were the cracked cylinder heads on 1800 svho or natural aspirated engines? And what years?
The one we were working on was a 2015 SGHO engine. The other two that we are aware of were around the same year or 2016 models. We think it may be a cooling issue as the machines may not have been adequately cool down before getting hot and then shutting them off. One machine that was spared, routinely ran the engine in cool water for five minutes before shutting it off.
good night I'm from Rio, and I would like to know if you could inform me the right point of this engine?
We’re not sure what you mean by your question. What do you mean “inform me the right point”?
@@3ftDeepChannel And the explosion point in the assembly of this engine
Question on the part of video omitted where you "loosened the transfer shaft" .Using the tool to hold the Cam shaft in place, did you use a 12mm allen wrench to loosen the special nut first to back out the transfer shaft second, or did you use the shaft removal tool with the spline teeth to remove the whole transfer shaft? Or is it the special nut that completely backs out to allow the transfer shaft to be removed. I've broken a couple tools at this point attempting to loosen the transfer shaft and special nut....hmm
To be honest it's been a few years and this is the only Yamaha I have taken this far apart so I can't remember all the details I do recall the transfer shaft took heat to help break the thread locker and a big breaker bar to get it to break loose. I think the green thread lock used during assembly is stronger than the red so heat is required for disassembly.
Do an episode on how to remove broken SeaDoo stretch bolts from 4tec engines when the torx head shears off!
Sounds like you've had some experience with that ...
Show ! Como está vídeo me ajudou ! A 1 ano atrás pela 1 vez veio veio um moto náutico para minhas mãos e hoje não para de chegar , Hoje sou especialista nessa área faço adpitacao de Bronzes recuperação do virabrequim , adpitacao de camisa de cilindro ETC ...
Isso é fantastico! Parabéns e esperamos por seu sucesso contínuo.
Is it possible to engrave the cylinder to a larger piston size? The original is 86 mm and needs to be engraved for an 86.5 mm piston
You will need to speak with a local machine shop about that. Good luck.
Is this project still ongoing? really enjoyed the other videos
Sorry, it's on hold indefinitely. The owner passed away. His family may want us to rebuild it at some point, though.
So sorry to hear that.
If water ingress was from towing in, why is there an emulsion of oil/water....that engine was spinning water around before it locked
We’re not going to spoil it by giving you the answer, so please watch “Part 5 of 5” to get your answer.
yes .... 100 % correct 👍
Good video,when assemble again
Thanks. Unfortunately, the owner passed away and we don't know what happened to the machine.
I’m looking to buy a jet ski.. who makes better engines and overall machines.. Yamaha or Sea-Doo? It would be my first jet ski.. I’m looking at something 2018 and up
We’re going to produce a video on that topic sometime this year, but it’s not a simple question to answer. All three major manufacturers do a very good job. Kawasaki‘s have a good hull and are good for longer distances and chop, but they’re relatively bulky. Yamaha’s used to be reliable, but we found a lot of serious engine problems with the more recent SVHO models. Sea-Doos have been very reliable over the past 12 years, and in our opinion have far superior looks and ergonomics.
I am doing the same work as you but in a 2013 vxs I need to remove the tranfer shaft as I loosen it??
Sorry, we don't understand your question.
Hey I have that same engine and the flywheel is loose and I don’t have a way to take out the central shaft because the whole engine turns and I have the whole kit to take it out is their anyway you guys can help me?
I'm not sure how we can help you, unless you live near White Rock, British Columbia.
Salve nobres companheiros! Aonde consigo esse jogo de sacar ?
A qual jogo você se refere?
hey, could you please post the part# for special $$$ tool needed to remove flange .. thanks
Sorry, we looked and looked but we can't find the part number (it was in the service manual that was loaned to us). It’s a Yamaha OEM tool, though.
Where can I find the kit for the impeller removal and coupler removal tool?
Good question. We borrowed ours. I suggest you check eBay and if you can’t find them there, try your local dealer but you'll pay through the nose. Good luck.
I don’t know where to ask this but I have a 97 sea doo, we rebuild the engine and it cranks good but we aren’t getting any spark at the plugs, do you have any pointers on where to look for the problem?
Thank you for your time
Willy Rempel tried putting in completely new plugs?
What is the special tools part numbers?
Sorry, we no longer have the “special” tool so don’t know the part number. We suggest calling your local Yamaha dealer to ask them. GOod luck.
I got the coupler flange off but need to loosen the transfer shaft. In this video it says you previously loosened it. Is it just a 12mm Allen key? I am
Just trying to get the flywheel cover off, that’s all
I honestly can't remember I have not done a lot of work on Yamaha PWC engines and this particular one did not get reassembled so the details are hard to recall.
@@3ftDeepChannel roger that, I appreciate you for doing the videos on this or I wouldn’t even have made it this far
May I ask where you got the tool to remove the flange?
We had to borrow it from a friend who worked as a Yamaha mechanic. Hopefully eBay will have one for you, if you need one. Good luck.
I have a 99 sea doo and it’s has 65 psi compression and it has no power what so ever, do you think a top end rebuild would be enough to fix that? And I have never worked on PWC engines before but would like to learn a little about them
With a machine as old as yours, it's very difficult to say. Those old 2-stroke engines can have lots of problems at this age. I would invest my money instead in getting a newer 4-stroke engine. Good luck.

Engine is toast
Why didn't you show the removal of transfer shaft ......
If I recall we had a lot of trouble with that. We had the camera off during that part, too much grunting and swearing!
I know I had to to it , I had to use two 4 ' stainless steel pipe with welded D link to it and a 6 ton chain hoist between them to brake it free... a 3/4 " braker bar..... and mag holder tool centered... it crazy how difficult it is to free that thing up..
Crikey Margarito! Thanks for sharing.
Is there any timing marks
Yes.
Nice work, question, how did you loosened the transfer shaft?
With great difficulty. If I recall we needed a special tool and a lot of muscle.
I have everything apart, your videos made real easy, but the only thing that I need to take apart is the transfer shaft, and I can’t find any special tools for that
We borrowed our Yamaha tools from a friend. You might be able to find what you need on eBay. Good luck.
Actually I don’t need to take apart the transfer shaft, I thought that it came off in order to take the generator cover out, then I realized, that the cover slides off 😁, thanks for your reply and again, great videos
Do you find the Bombardier or Yamaha stuff easier to work on for a home garage kinda person?
Good question. We've noticed some things are easier, and some are harder. For example, it's easier to take the Yamaha engine out of the hull, but more difficult to take the engine apart because of the driveshaft coupler. So getting the engine apart is much more expensive with Yamahas. Overall, for most jobs I'd say they're about the same.
3ftDeep Thanks. Been contemplating a used PWC purchase and have been trending Bombardier because of channels like yours and active online forums that make asking questions really easy.
What tool kit do you use?
It varies. You can find the types of tools we use at our website store here: 3ftdeepsports.com/store/
Have a link to where you have purchased tools to change Coupling I'm going to change My stator
We're going to try to put up more links to tools. We used to have our own "eStore" that was hosted by Amazon, but the service was discontinued. Thanks for your comment.
@@3ftDeepChannel Can't tell me what tool number I should write to order the tool you user
Ok i watched to the end and i stand by my original conclusion.
Watch "Part 5 of 5" and then let us know your thoughts.
@@3ftDeepChannel yep watched it again and water does not bend valves and only one piston was broke so how did the other valves bend? It was becouse of the rust on the stems like i said before . and i dont really care if you believe me or not . one piston did not bend all the valves .
I'm not saying you're wrong. Just wanted to make sure you knew that the cylinder head was cracked. What you may not be aware of is that rust could have formed after the piston failure, as the machine sat for months before we made the videos. We may never know, but this machine is the third "newer" Yamaha of our group to have a cracked cylinder head. They 3 failed within 12 months of each other. Thanks for your comments.
@@3ftDeepChannel yea i understand what your saying iv seen and tested 1000s of cracked heads that never leaked , most dont have water jackets in the combustion area how do i know this well iv cut the heads in half with a band saw testing and investigating.but i do see the same valve problem on direct injection motors no fuel to clean the valves.thats on automotive and marine.we may never know on your engines
All the valves were not bent just the four in the cylinder with the damaged piston the piston skirt broke which caused the piston to flop around in the cylinder and bend all four valves the valves in the other three cylinders were not damaged. We figured the cracked head caused water ingestion in the oil which caused a lack of lubrication and this piston skirt was the first failure point.
How did you loosen the transfer shaft ? is there another special tool to be used?
I can't remember exactly it's been a few years I think you have to hold the crank then use the spline tool to loosen and remove the shaft I know it was on there ridiculously tight.
@@3ftDeepChannel
Thanks . Yes it was soooo tight i had to use a 4 ft breaker bar .
Well , again thank you for these great videos !
