Thanks for the reply. These machines have low hours but weren't checked out very well by the dealer we bought them from, so I guess I'm going to be doing the maintenance on them. I read a couple of threads about the instruments and some cycling of the connections and contact spray might get the readings back. Do you change you own oil? If so, what kind of dipstick sucker should I buy. I hope my wife doesn't find out I'm typing like this. We are in Montana and have a short riding season and the water we ride was ice a week ago. We will be careful about warm up in the future. We do like these boats even tho they are 400 pounds more a piece than our last boats. I'll read more of your posts, and thanks again. Tom
