Damn you GG, I was trying to hide the fact from the young fellow that when I take out a shear pin it is NEVER before the ancient propeller is mangle-blade toast. As a carefree youth, I early on confused small outboards with roto-tillers, and there comes a time when one just plain runs out of shear pin propellers and there ain't no more..

Alas, I am no stranger to something like that "African Queen" sequence where Humphrey Bogart has to make a propeller in the jungle. Hint: Wooden mallet is best. Easy on the heat. Hump was working with iron.

In future, FReepers, refer all mechanical guru type questions to well ... a a a like, you know, guru. Take over GG!

Perhaps, just maybe - iffn you hadn’t used 180,000 psi steel rod when that piece of brass rod was hidin’, meybe the pin might not have kept on a grindin’ ‘til only the maufacturer and you knew which size that prop was when it left the factory.

Humor aside, the 7.5 air cooled could operate without the water pump retaining its vanes. All it did was pump enough water to keep the lower crankcase sear from reaching thermal destruction. It was a nice motor for pushing a flat bottomed canoe through the shallows west of Cockroach Bay.

Noisy, but could push through mud, algae, assorted ancestral habitats of Democrats.
