I have a 1978 Yanmar 2QM20
in My Nicholson 31. (knock on wood) it runs perfectly, no oil consumption
, clean exhaust
etc. Has original alternator
and would like to upgrade to something like the Balmer 60 series 70amp. Should I be concerned the larger althernator will place too much demand on the engine
? Any other considerations iI should be thinking about? Bob V.
