What size prop pitch and size are your running I have the same motor

[@330da]

It’s a Yamaha Original Performance 4-Blade SSTP. 13 1/4 X 18 K MAR-GYT4B-V4-18 Great eco low rev plane speed (2600-2700 rpm) on my 500 kg Yamarin boat , though to big a prop for top end speed - ,,, A 3-blade 17” or 18” prop Could give maximum top speed on my boat without trimming so ridiculously much. With 4 blade propeller, 37.5 knots, ,,, With a 3-blade 17 "18",, over 40 knots,,, but then i have to sacrifice the low rpm eco plane. Best reg, 330dA
