got a mate of mine who has just bought a 20ft searay,with a 4.3 v6 merc/alpha drive. its got a high five prop on it at the moment.does anyone know what size a 3 blade alpha prop would be best suited,cheers
Im turning a 19 on my wellcraft 21 at the mo with a volvo 4.3 and its underpropped. I need to drop a couple of hundred RPMs so reckon a 21 would be about right, maybe even a 23
