[QUOTE="user 26281, post: 476551, member: 26281"] I have the 2016 DF9.9BT and have converted to 20HP. I installed a flame arrester first, and got probably 15HP (17mph) or close, but the engine would go into RPM limiting at WOT. I then installed an induction tach and found the RPMs slightly high, so changed the prop (increased the pitch). Still had RPM limiting at WOT. I then replaced the ECU and no RPM limiting at WOT. Speed increase from 15mph (6000rpm) to 20.4 mph (6320rpm) WOT. Flame arrester - $15 Induction Tach - $20 9 1/4 X 11 prop - $40 ECU - $285 [/QUOTE]
