Motor mounts?
I know the stock 4Tec motor mounts are a bit mushy to surpress the vibrations and such. How do you know when a mount breaks?
I can tug on the engine and make it move a bit, tried pulling up the front of engine by hand moves a bit that`s it..
wouldn`t the carbon seal leak like a stuck pig if a motor mount broke?...
someone tell me...PR...

Andy, They are just rubber composite and there will be a very slight movement. You'd know if it was broke. Just shine a light on one of them while lifting or shifting the motor and you'd be able to see a crack. That motor would move quite a bit then. You would definately wear that carbon seal out if that drive shaft was banging all over it from a broken mount.

By very slight I mean that if you "REALLY" yank on the engine you should barely see any movement at all. If you see a noticeable amount of movement on any 3 points of the motor mounts, I would check that area. Put your hand on the mount itself and try to feel for a crack, use a small mirror, and shine a light all around them including the hull where it mounts to. You may have a crack and it is not noticable right off.

I was surprised how soft they were.. I can see why the high HP applications we run are to much for the OEM motor mounts. Or better yet, to much to risk! as I found out the hard way!! Nothing worse than a ride back to shore, pulling your sinking jet ski..
