Evinrude Vintage Outboard

[jwg710-gmail-com]

I would like some information concerning an old outboard motor. The only number I could find on the motor is 4091-7688. It has the name "Evinrude Elto" on the top. I’ve been told that this motor may have been made in 1935 or before. Any information concerning the age of the motor and its value would be greatly appreciated. I’m unable to attach pictures here, but would be able to send them to an email address. My email is jwg710@gmail.com.

Thanks,
James Green

It is a 1935 Sportsman – first outboard with a reed valve. Introduced in 1935 as one of Ole Evinrude’s "hooded Power" outboards. Inch and three quarters bore and an inch and thirty five sixty fourth stroke . . . 😎

Removing the plug in the bottom of the fuel tank (which I recall held a fuel filter) reveals the check valve on the end of the fuel pick up. If it leaks or sticks shut the motor gets no fuel. The drop in crankcase pressure as the piston moves toward the spark plug opens the reed valve and pulls fuel up into the carburetor bowl. Surplus overflows back into the tank. There is no float or float valve. It uses a short spark plug to clear the motor cover. Some left the cover off and used a standard plug. A lost cover cuts the price of the motor in half. Running in polluted or sandy water is hard on the brass piston in the water pump. If it wares through and stops pumping, the standard fix was to solder a copper penny on the worn part of the piston. Good luck on that one . . . 😆

Thanks very much for the information. I would also like to know if anyone could tell me the value of this motor and if anyone would be interested in buying it.
