Can one propeller give top speed plus lots of power? |
Generally no. To gain high speeds involves sizes or pitch ratios unsuited to load carrying or working conditions. Decide what is most important and select the prop accordinly, or change props with boating conditions. |
I have a right hand rotation prop but need a left hand rotation. Can it be changed? |
No. Propeller rotation cannot be changed. Turning it around won't change the rotation. |
What benefits does a cupped-edge wheel offer? |
Cupped-edge propellers for fast boats and high rpm reduce slip, giving as much as 3 mph more speed on the average, and eliminate cavitation. |
How can I tell if I need a left or right hand prop? |
Stand in back of boat. If shaft turns clockwise, a right hand prop is needed. Most maring motors take right hand props. |
A prop larger than I can swing is indicated for my boat, engine, and gear. Should I use as larger diameter as I can and add pitch to hold motor rpm down? |
Change the gear, increasing shaft rpm, reducing prop diameter requirement, or, change shaft angle or prop aperture to accommodate correct size. If impossible, use a wide 4-blade prop for diameters 18" and up. Under 18", a 3-blade, larger in diameter than required, can be clipped to maximum usable diameter. |
