Q:

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?
A: 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.
