Help, I want to winterize my jet ski after the summer season and can I do it myself. It is a 1998 TS 1000 Tigershark . My neighbors who have Sea Doos are doing it but their engine is a little different than mine. The manual has some instructions but they seem long and complicated. When I take it to the dealer they have it done in a few hours. There must be some simple shortcut to getting it done. Thanks.
