So like $600 rebuild vs $900 new + warranty... I'd probably go new and I agree that you should do a total refresh while it's out for peace of mind
Especially after reading some about your crank. Evidently is has its bearings pressed on and requires balancing after being rebuilt. If your machine shop is comfortable with doing this - they should offer you a warranty of some type but I'm going to guess that most machine shops aren't rebuilding these often?
they are fun little motors. if you ever come across one.
i like the warranty idea. i'm pretty comfortable doing things myself, but like you said, the crank has to be aligned so i might as well have someone do it for me.
i am really curious as to why it failed. i idled it 2 miles back to the dock and it didn't really tear anything up. thinking about it now though, one of the rods got over heated and is discolored. i think it's best to swap it all out.
for another 400 i can get the premium motor with a 2 year warranty. http://www.shopsbt.com/seadoo_jet-ski_engine_premium/P40-107.html
seems like a lot for only an extra year. i do put 40+ hours on it yearly though. it may be worth it.
