The Rhaas aftermarket engine mounts that are illustrated were used on a Sea-Doo with a stock engine set up for Pro Stock class. The initial height of each engine mount was 8mm however after the use of approximately 40 hours the height was lowered to 4mm at the sides (and not radialy from the center). Has anyone experienced a similar issue? Due to the warranty the company offered t the customer a brand new set of engine mounts.
