I've been currently running a worked 25 tempest plus worked by Mark with pretty good results. With 50 gallons of fuel, and a full tournament load I was at 5900 Rpms getting 72 to 73 mph. Until today when It threw a blade. My question is should I go back with a worked 25 tempest plus or should I try a worked 24 tempest plus? I make long river runs at times so that should be considered. Would the 24 help me pick up more speed? Should be noted when I'm alone I can run 75 to 76 around 6000 Rpm fairly regular with the 25. The worked 25 tempest plus that I had was put to stock with added cup..
The prop that came with the boat was a 25 fury. Today at full tournament load was 5650 around 70 to 71 mph..
