[electricboats] Trolling Motor Propellers (was: propulsion Navy 3.0 Propeller Dimensions)

The early Electric Paddle outboards used model airplane propellers, and
the current models use props very like those on model airplanes:

The trouble with putting better props on trolling motors is that the
submerged motor blocks a big part of the center of the prop...

A friend of mine got a couple of these plastic emergency props to try on
his twin 80 lb. thrust trolling motor drive, but the clearance under his
boat is so small he'll have to trim the diameter quite a bit:

I think Merc has discontinues these...

Winter, a lingering season, is a time to gather golden moments, embark
upon a sentimental journey, and enjoy every idle hour. (John Boswell)
