Re: Propeller Ted Williams 7 1/2 hp
I don't find that number You may want to double check
I find 574.60600 and 60610,Could be Canadian.It is a McCulloch motor.It appears about a 66.
There are weedless drive and straight drive lowers.Straight drive has an obvious skeg with a straight leading edge the weedless has a morfed skeg
with a curved leading edge sort of blended into the gear case.
Don't know if props are different.ebay would be a good start for a prop.
