09 SHO rattle

[shore]

looked at an 09 SHO today, 122 on clock. Started ran just fine. Heard a rattle at idle. Could not hear it with any throttle over right above idle. Ran right out to 67.

Popped seat and let it idle in water...sounded like bad bearings in the SC. I passed of course but the guy went home and pulled the SC and put another one on. Same noise. Said the dampener has some play?

You could hear the SC slow down when I shut it off. Almost sounded like bad bearings.

I've pulled sea doo SC but never had an issue with my SHO blowers?


any ideas on this or?

Probably just the SC clutch. Its normal

I had an 09 SHO a couple years ago with 45hrs and in no way did it make that noise.

Explain why when the engine is shut off you can hear the SC whine down for a few seconds? It sounds just like a turbo when turned off but a bit more mechanical, if that makes sense. A little more metallic sounding.

It's normal.......its gear driven

I listened to a couple on youtube, similar but louder. I seriously do not remember this making this noise on my last 09.

Normal

You are telling me it's normal to hear clatter through the seat while riding in the water at idle. I started it and immediately thought the valves where out of spec. Like marbles in a can. Touched the throttle and it was almost all gone.

driveline damper might find black rubber teeth in the bottom of hull
rod bearing run with seat off you can hear it when coming back down to an idle

It is excaclty like a turbo winding down after you shut the engine off. At idle the super charger is spinning at 13,500 RPM and it does takes a few seconds for it to come to a full stop.

Had an 09 FZS and a 14 FX-SVHO now and they both sound identical.

The he noise is gone imidiatly once you put some load on the system.

Good luck, Julio...

as said already the noise is most likely the normal sound you hear on all of them
if it stops making the noise it usually means the clutch is gone
