Hi. I have a norwegian displacemeant / semi displacemeant Tresfjord 26 boat and im thinking about chancing the propeller. 8m long (waterline is 7.4m) and 2.8m wide, draft is 1m. Boat weights 2500kg fully loaded. Beta engine is rated 43hp @2800rpm, prm 150 gearbox is 1:2,09. It says on beta's website that the right propeller for beta 43 with gearbox ratio of 1:2 is a three blade 18x12. Would a 3 blade 18x13 propeller be over pitched? What kind of propellers do people have with this same engine and gearbox setup and what is the achiavable max engine rpm. I dont want a propeller that is oversized and i wont be able to reach 2800rpm My current propeller is a vetus 3 blade 16x14 and im getting maximum of 3000rpm and at cruising speed my propeller slip is 40% Regards Henri
