Hi - really hoping y'all can help me. Have a new Beavertail Strike w/ 90 Etec. Boat came with 4 blade powertech and was only hitting 5000 rpm and 38.5 mph, hole shot was sluggish and boat did not accelerate like it should with this type of power to weight ratio. Tried a 3 blade Etec viper 17'pitch and got a slightly better hole shot and 40.5 mph, but still only hitting 5100 rpm when jacked and trimmed to the max. Feel like this boat should hit 41-44 mph at 5500 rpm...does anyone have any feedback on best prop for this setup? Thanks!
