I have owned this ski for 10 years. Ran flawless until last year when my sister didnt put the plugs in and flooded the hull. Upon looking it over i discovered the oil seals around the crankshaft were shot. So i broke down the engine and replaced the seals. Ran real good for 2 days then yesterday was running fine then at wot it died leaving me in need of a tow. Opened the hood the seals are blown again. I picked up the service manual and discoverd te seals should have been greased on install i didnt do this. Is this why they blew or is the crankshaft bad? I didnt feel any shaking when it was running.
