weird carbon ring wear causing water leak. Riva Stg 3 RXP

[synergy141]

I had a water leak on my 2004 Riva Stage 3 RXP the first ride out after buying it. Previous owner said that the carbon seal was replaced recently. I pulled it out and it had uneven wear and grooving in it, causing the leak. I also noticed the drive shaft rubber knob at the motor end was crushed and deformed. What would have caused all this?

-Improper install?
-Engine alignment off?
-Motor does vibrate alot at idle for some reason

broken motor mount

-Motor does vibrate alot at idle due to all the mods

Motor should not vibrate at all due to any mods.

broken motor mount

I agree! The vibration is caused by a possible broken mount
This would also be the cause of the carbon ring wear.

I have the replacement carbon seal parts and mounts for the 04 RXP on this page of the forums store if you are in need

I will inspect. He told be it vibrated because it was "built" lol.

Edit: Motor mounts are good and solid. When these fail does the rubber break in half completely or do they just become soft and have play?

Normally when the mounts fail, the metal portion separates from the rubber. They don't go soft.

In that case what has probably happened is that rubber plug on the end of the driveshaft split which causes play in the drive shaft and can result in uneven carbon seal wear. It's very important that you check engine alignment once you get it all back together.

Okay, and should I be replacing the rubber bellows and metal collar at the same time?

Bellows should be fine but it wouldn't hurt to replace it. Same with the top hat. You can reuse the top hat by resurfacing it using 220 grit sandpaper on a flat surface.

I never run the engine out of water for over 1 min when I wash the IC on my rxpx 2013

Yes, you will absolutely want to replace the rubber bellow also as they lose tension over time. especially on a 2004 ski.
Replace the collar and circlip also and the two o rings that go inside the collar. Basically, you want items 37, 36, 35, 34, 40 and 41 on this page of the store
