    Inspect your motor mounts..

    Just a heads up guys as I was changing out my SC belt and sliding the engine a little forward noticed it was cracked on both sides sitting on top of the metal shim and now was completely separate from on top of the shim, notice it cracked last summer but not severed completely ,after having more visual now that the engine is 2 inches forward there's another mount that had a crack too though not completely torn.

    Ordered 2 from the dealer ($50 each) so I realize its something probably should be on everyone's pre ride check list like checking oil and clamps so you're gonna have to get in head down deep in that hull with you're flashlight give a good look and feel..

    The rough water pounding all these skis take I'm not surprised it doesn't happen more frequently..

    Did you notice more engine shake than usual?

    No.. Then again on the trailer flushing the ski and feathering the throttle 3-4000 rpms won't show much movement,on the water WOT nothing.. but I believe I severed the one completely moving and aligning the engine base brackets and holes..

    Wow, I have never seen a motor mount do that. It might be a good idea to just replace all 4 of them. With one severely compromised like that, some unusual torque may have been sent to the other motor mounts as well. JB

    Let me look up the company, there is a group called rhass I think that makes some seriously sweet mounts, kawasaki included. They have a lifetime warranty.

    I bought some mounts from Rhaas for the pipes in one of my skis. Very high quality urethane parts.

    The mounts for the Ultra 150s are known to fail. I replaced mine at about 150 hours. I think jumping waves really takes a toll on them. I would expect the 4-stroke Ultras to have the same problem.

    I would not use a urethane motor mount unless you want to transfer every bit of energy and vibration directly to the hull and vibrate every screw and bolt in the hull loose. Factory clevite style mounts are what you want.

    I honestly do not know too much about the urithane ones from rhass, the stand up guys seem to like them though. They offer 2 materials but like mentioned they could transmit a lot more vibrations/energy.
