Re: proline 251 repower questions ? need advise or answers
I repowered a 232 Grady gulfstream last year and Put on 300 Suzuki. I get 30 mph at 16 Gph. Top ends low 40's. At 6k. With different prop (3 blade)I got 47 mph at 27.5 gph. Top end. Current 4 blade is fast out of the hole but slower on top,end. Purrs like a kitten quiet and dependable. Boat weighs aprox 4150 plus hard top plus 20 hp,kicker and 148 gallons fuel. My guess is 5.5k fully loaded up.
