3 or 4 blade props?
The most economical cruise is going to be at the lowest rpms and maintaining
plane. A 4 blade will allow for a lower rpm than the 3 blade at minimal plane speed. It will also give you better throttle response and quicker planing. -- Tony My boats and autos - http://t.thomas.home.mchsi.com "F330 GT" wrote in message ... For this application, good performance SS 4 blade props would be the best choice. They will give you better acceleration, planing speed, and low speed cruising ability. You will loose a few mph on top end but chances are your not trying for top end speed anyway. You will definetly like the way the boat behaves. Prop for right at max rpms on the engines at wide open. Don't waist your money on aluminum 4 blade or composite 4 blade as you have too much torque for these props to hold their shape over time. -- Tony my boats and autos - http://t.thomas.home.mchsi.com "Diver1055" wrote in message ... Hi I have just purchased a 2950 Proline with twin 225 OceanRunners. I am trying to get the best economical cruise speed I can. I was wonderig what would be the advantages to a 4 blade prop as apposed to a three blade prop... Thanks Rick Tony, I don't disagree with the response as far as the qualities of 4 blades but he was asking for the most economical cruise. I can't imagine a 4 blade being more economical than a 3. Common sense tells me there would be less drag with one less blade. Barry |
