sail drive part of the package because my boat is full feel so that half of the maintenance isn't in question. The cost of replacement parts is interesting. You always her of Volvo parts being expensive but this is the first time I've heard Yanmar mentioned. Maybe it's because I had a Volvo and I'm tuned into it when I hear Volvo. Volvo parts are just crazy expensive. I rebuilt my entire Perkins for the cost of an oil filter. Well, maybe not quite, but close. I guess it going to boil down to what fits but it's nice to hear positive things about the Yanmar because it opens up the option.
