Rep Power: 11
I am repropping from an 18 x 13 fixed three-bladed to a 19 x 15 (nominal) feathering four-bladed VariProp because I hit six knots in flat seas at 2,100 rpm or so on a 52 hp Westerbeke and I think my power curve would be better swinging a slightly beefier prop. I don't care if I lose a touch of speed, but for maneuvering under power, I believe the new prop will provide more stopping power in tight quarters. This has been very much the experience of a friend with a big steel boat even heavier than mine who put an 18 inch AutoProp off a 35 HP (yes, too small) Volvo...his boat started parking like a minivan.
Also, I can adjust the pitch if I find I am taxing the engine overmuch, but I don't think that's going to be the case.
