YES. IF your svho powered waverunner from 2014 or 2015 has not yet snapped its timing chain, you can purchase the new and improved timing chain assembly kit for 1500 dollars. If you wait until it snaps----which I did.....its an 8-10k price tag for the dealer to replace your entire engine. When my chain snapped at 53hrs, I was still under warranty and it was still hell to get them to fix their defective designed engine. and it was a bad design as evidenced by the totally redesigned 2016 svho engine timing setup. And by the way, it is very sleazy of Yamaha to act like this is a rare occurence and not something serious enough to warrant at least sending owners a lousy noticed. Me and my passenger were bucked off at 65mph when my chain snapped right as i was crossing a tiny boat wake......the decelaration was at least 2 or 3 Gs (yes I know because i"m a pilot and have to avoid anything higher than 3 gs if I don't want to die.) Had I gotten a letter from Yamaha I would have either sold the fzs and bought the 2016 model, or I would have had the timing chain assembly updated to the new design at my own expense. Now I will be left with a seriously compromised brand new skii. I was in saltwater when it broke and thus it could not be flushed.....Yamaha let the thing sit for months full of salt before they got it all torn down. I'm getting mostly new engine parts but I'm guessing there will be mechanical gremlins for the forseeable future if they ever even fix my waverunner at all. I'm paying 500 a mont.....6k a year and this year, I spent 6k on something that I only got to ride 30 minutes this whole season......dumb luck had the machine fail at the very start of riding season....I'm guessing I'll get the ski back after the first winter blizzard sets in.Can I fix this before it happens? I have a 2015 svho engine.
Slugger55 if you are going to purchase now it should be fine apparently they upgraded the chain in the latest model skis. Some say this is a cover up, while others say not a cover up and for 2017 they are making a serious hp ski that require the heavy duty chains so they are putting them in current svhos now. I'm waiting on more info from my friend.
When you get the 411 please share. I talked to my wife this morning about making a purchase. I would rather have the SVHO vs the SeaDoo...
Sounds fine. LOL. Seriously.10 hours on my new ski is this a timing chain issue or something else or normal, I have a hard time believing it's normal used to work as a mechanic and never heard sounds like this coming from a motor.
this sound was almost from day one. The first day we took them out was for an entire tank of fuel. 50 mile ride up and down the river . Thanks for any help
Sounds fine! You are hearing impeller noise from the pump.10 hours on my new ski is this a timing chain issue or something else or normal, I have a hard time believing it's normal used to work as a mechanic and never heard sounds like this coming from a motor.

That's normal sound of the supercharger in these boats/PWC's. You can hear mine at 10:22 in this video10 hours on my new ski is this a timing chain issue or something else or normal, I have a hard time believing it's normal used to work as a mechanic and never heard sounds like this coming from a motor.

I am just not ready to buy a 1.8 boat. This makes me very sad.Hi guys!
Same issue here... TWICE!
So At 26 hours, the fist chain went.
mine is a 2014 FZS SVHO, bought it in august of 2015, used it for 2 months and stored it.
June of 16, the first chain snapped.
Yamaha warrantied the job, no issues.
Ski sat at the dealer from july-September/16
When they finally gave me the ski back, they said Yamaha had sent them a "short block"
I took it to the lake, before I started it, it had 27 hours.
At 27.1 it stopped again.
Back to the dealer to find out the chain snapped again.
So it is now the 3rd motor, in 3 months of use.
Yamaha will not replace the unit.
They did acknowledge the unit has a faulty motor.
Today, the dealer called me again. (10/15/2016)
Yamaha sent a sealed power unit.
When they went to lake test it, the unit won't go over 40mp/h....
They told me the supercharger is now gone...
Tuesday they will get back to me....
SHAME ON YAMAHA!
If the low speed engine noise sounds like marbles rattling around inside the engine, that is normal, oddly. I can't comment on the super charger. The issue with the timing chain failure is there is really no indicators of any impending failure. The is an upgrade kit you can purchase, but I think I saw a price of about $1500 for that, so not cheap. Otherwise the only really options are to cross your fingers or sell unfortunately... I'm in the crossing my fingers group for now.Wow, I just bought a 2014 Fx SHO(not an svho) yesterday and just came across this thread.
Is my engine at risk for the same issues? Mine has,46.4 hours on it. I haven't even been on a test ride yet.
It is noisy at idle. And when I turn it off I can hear the supercharger still spinning for a bit. Clutch issue?
Any advise would be great.
Thanks guys n gals....
Yes it is.Is the timing chain issue common to the SHO as well?
Personally I would go with the Seadoo because of the closed-loop cooling since you are in Florida---less wear and tear on the internal side of your engine. We are constantly cleaning out peoples cylinder cooling jackets here in the Fort Myers area from excessive sand, shells, debris etc. The ports for cooling on the Yamaha's are very small. Be religious about flushing, and don't beach it--Only Baywatch gets new PWC every episode, you don't, lol!When you get the 411 please share. I talked to my wife this morning about making a purchase.

You still need to flush a Sea-Doo/closed loop system --- just want to clarify that for future readers. The heat exchanger still needs to have the salt water flushed or the jackets can become clogged or corrode through and you end up with water in your oil. Yes, better here than in your engine block, but still a costly mistake.Personally I would go with the Seadoo because of the closed-loop cooling since you are in Florida---less wear and tear on the internal side of your engine.
