The boats and PWCs use lots of the same parts. The motors and pumps are all basically the same with very few changes. You will finds just about every repair/winterization video will fallow both the boats and PWC's spread across many years of watercraft. I find if you are looking for a particular video find one that has the same size engine and you can easily follow along.
Thanks for the info! That what I thought but wasn't sure, no I was just looking stuff in general I guess. I think I will probably be doing the carbon rings before spring so just looking at different stuff on them and other things
