A benefit of replacing your old Jet Ski mounts with our motor mounts is that the excessive vibration and movement of your Jet Ski engine will slowly degrade the rest of your driveline, bearings, driveshafts, etc.
Replace any motor mounts that don’t appear normal to save the rest of your driveline!!
