I have a 1974 pearson 30
, repowered with an 18hp volvo
diesel. (was A4 originally)
I have on it a 14x12 2 blade
. There is maybe an inch of clearance from the hull
, certainly less than optimal.
IMHO, the prop doesn't give enough thrust. The engine is never under stress, and I must rev high to get any speed. I don't like revving over 2000 (noise, vibration, wear, etc), so I end up going less than 5knots most of the time, and less if there is a headwind.
I'd like to get a bigger prop, but there's no space for more diameter. I'm considering going 3 blade. Any suggestions?
