Feathering props have a large central hub to contain the gears, etc. Your small engine
won't swing a very big diameter prop, and I suspect that the shaft to hull
distance will also limit the max diameter. So, between these factors, blade area is quite limited with a feathering model. In fact, you may find that there are none that will actually suit your boat
Folding props will allow a better disposition of blade area and are also more efficient due to better blade profiles... but I'm not sure that even a folder can be found for such a small engine
. Have you done any research
on this proposal?
While I'm a big proponent of folding props, I'm not sure t hat it is gonna work
out for you. LEt us know what you fine.
