A good friend is a retired
diesel mechanic with 50+years of experience. When he mentions
Westerbeke it's usually preceded by an expletive. Says they are the worst of the worst from mechanic's POV. Use a bunch of different base engines, disguise the makes and models, use hodge podge approach to add-ons, gouge on
parts, etc.
I'm happy with my original Universal 5432 but if I had to re-power no question I'd go with Beta 38. Hands down over other choices, with their electronic doodahs giving up the ghost in just few years of salty
environment.
