Ok my fiberglass 17' 89 Ranger 373 doesn't have the right prop on it. Currently has a 14.5 X 24 3 blade. It's a little sluggish out of the hole and sucks at keeping low speed plane. And does about 60 (according to the gauge) at 4600 RPM's. What is a decent inexpensive prop and where can I get it. I'm hoping to keep around 58-60 and definately improve low speed and out of the hole performance. I'm guessing that probably means I should consider a 4 blade prop. Any advice is apreciated.
