I have a 1999 Rinker Flotilla Deckboat, 24 ft (approx 3500 lbs) that I finally got in the water after four years (project boat!) I got the boat with no engine or outdrive and I installed a Marine Power 5.7 (fresh rebuild) and a Volvo Dual Prop outdrive (DP-SM 1.95) I took my best guess at the proper prop and put on stainless F6 prop set. The maiden voyage went well considering the extensive work I did on the boat, engine ran good, steering and trim all good, most of all no leaks! The only thing that was disappointing was the lack of a hole shot. According to the manual on the engine it is rated at around 300HP, however when I push it quickly to full throttle it bogs down and struggles to move out. If I bring the throttle slowly up to around 1000 tom 2500 RPMs it really scoots. At 2500 RPM I was running around 32 MPH. I can't go above around 2800 RPMs or it bogs down. So my question is do you all think I selected the wrong prop and if so which way should I be headed, lower number, F5 or F4? Another note the prop set I have as reconditioned by a fairly reputable shop so I believe the props are in good shape.
