Had a Volvo
in our 20,000# displacement
Westsail 32 with a 2 blade
prop. Believe the MD2 pumped out about 24hp at max RPM
. We were happy with it. Engine
loafed going 5 knot cruise
speed and only burned a 1/2 gallon an hour. Boat
was overcropped so never managed to get it close to redline and don't remember what the max speed was. Usually motor
sailed the few times we had to power into a head wind
and sea but definitely over 6k in flat conditions. Not because the wouldn't go under power alone but could do the 5k cruise
with the engine
ticking over a little above idle, sipping fuel
, and sailing very close winded.
Did deliver two boats with 35hp diesels and 3 bladed props. Boats were more maneuverable largely because of the large 3 bladed prop. Not enough of a difference to make us pine for a bigger engine, though.
