62HP Performance
I own a P42 with a Yanmar 62 HP turbo-diesel. After two years experience, in all types of sea conditions, this is a GREAT engine. It consumes about 1 gallon per hour at 2800 RPM. The turbo comes on at 2300 RPM, so if you run it below this level, your fuel consumption will be reduced by about 1/3. Performance is relative to your prop size and pitch. We have a 3 blade max-prop with variable pitch. Set at 18 degrees, we power at 8 knots into moderate headseas at 2800 RPM. We have found this to be an extremely reliable engine, that just humming along.Hope this helps.
