Looking for proper prop for a 470 Alpha One 17' V-hull Four Winns Horizon 170

[natemoore]

The previous owner of my boat tried to compensate for a blown head gasket/worn out engine by (how you say) " propping down." He installed a 14 x 19 prop, which I'm assuming is a 14", 19 pitch. It's a single barrel carb, MCM 165.

At WOT, I'm only going about 25 KTS/hr. Some of you guys are going 45 mph on your 470s.

What props do you other 470 smallish boat owners have?

P.S. Did the knots per hour thing just to annoy you nautical sticklers.
