Hi all,
Just some info for you on a prop change in case anyone is thinking along similar lines.
old prop 15 x 17 alloy giving 38 kts at WOT 5500 ( 2 up)
new prop SS Rapture 14 1/4 X 19 giving 40.5 kts at WOT 5100 ( 3 up)
Noticeable advantage in retention of cornering speed which I assume is lack of ventilation, Haven't as yet experimented with engine height.
all in all a
Prop-er Job!
