I have Minnkota 55lbs on a 17' 1500lbs sailboat and it gets up 3.1 knots on
a flat water.
Same motor on a 9' hard dinghy with one person and the group 27 battery on
board gets 4.2 knots. I was told I could gain about half a knot by changing
to an aluminum "power" prop (~$30) and another half a knot if added a Kort
nozzle ($$$)
