Both rear engine mounts seperated

[OCD Solutions]

I was pulling the engine from my wifes ski last night and found the rubber on both rear engine mounts seperated from the lower mount. When mounts go bad do they normally just release like that or do the tear the rubber? Luckily she doesn't ride agressive enough to have done any damage but it explains why her ski kept shutting down on her the last ride of Daytona.

I assumed her idle was too low on her new carbs once the ski warmed up so I didn't dig into it too much, I'm glad I didn't jump on her ski and put it through the paces or I may have caused a ton of damage.

Since I'm tearing everything down from her ski for my new build with the SS846 I'm thinking of using a set of GP800 engine mounts I have on the shelf. They are beefier but with similar overall dimensions. I already have Carter Keepers so clearance shouldn't be an issue.

Anybody have any more experience with this? Jetmaniac has a post that says they are 1/4 taller but when I held them close they appear to be the same height. I'll unbolt one tonight and get a side by side comparison. Seesm like a very simple upgrade/solution to me.

every one that's let go on me - the metal piece just separates from the rubber (that I can remember)

The gp MMs are 1/8" taller and can be milled down and mount holes openned up to work.

Cool, thanks Tem

yep, same here..



I have been using GP800 mounts for the past 3 seaons in 2 different boats......didnt have to mill them, but did have to open up the mount holes...


dont see why you'd have to mill them when most boats need shims to raise the motor anyway..





ps..you can use Raider, venture or GP800 mounts (not sure about 1200 but I'd guess they're the same as the 800 mounts....)

So just open up the mount holes and set them wider apart then, gotcha.

at least dead couches are good for something!

broken mounts wont kill the motor

It will add load as it bumps around and binds the coupler and will cause it to stall instead of idle. I agree it wouldn't hurt it while on the power but it would die when she let off on the gas entirely.

and it will SHRED a set of driveshafts....

Luckily I caught it in time, coupler rubber wasn't even marked up at all. I will have to inspect everything before reassembly into the Matrix though.
