Thinking about repowering
As the present owner of a Isl. 32 MK II and a past owner of a Pearson 30, both powered by the mighty A-4, I would only consider repowering with a new diesel (Yanmar preferred brand up this way) IF I planned to keep the boat at least 10 years, more like 20. Difficult to recoup cost of diesel compared to a rebuilt A-4. I've been told the cost of a new diesel will be 2X that of a rebuilt Moyer A4, when you factor in new engine beds, et. Good luck!
