Greetings. I have a 1979 Hunter 30 with a Yanmar YSM-12-R inboard diesel. When we went to commission it for the season this year, the manual fuel pump stopped working. It would pump if we manually worked the lever but otherwise, the engine would start and die or not start at all. The yard's theory is that the eccentric shaft has worn to the point that it won't drive the pump anymore. It'd be a huge job to replace and they're suggesting that they bypass the manual pump and install an electric one.
Has anyone run into this kind of wear on an engine? Does it seem plausible? The yard swears that there's no down-side to the electric pump and that in fact it will work better.
I'm hoping someone has experience or opinions on this.
Thanks,
Mark Berns
