A beautiful day on the water today. With most of the fair weather boaters already winterized, I was out today with very little traffic. With a 5-8 knot headwind, a nearly full 60 gal. fuel tank, bimini down, and about 600 lbs. of people / gear on board I was able to reach 40 mph @ 4000 rpm w/165hp I/O with 21 pitch stainless steel prop.
