Evinrude made a 2-cylinder "3" HP? Wow, whats
that got, like a 1-inch bore per cylinder.

Very common motor in its day.

Thats cool.
I have the number for the dude on the East coast
that bought up all them Force/SeaKing parts if
needed. And yeah, stay away from the Clinton.
The Force's in the late 70's, early 80's had lots
of problems with the crazy spool-gear type recoil
starter, and such, but when a motor is free, money
spend for parts is not so bad. Speaking of old motors,
I recently did a full rebuild of a 1974 Sears Gamefisher
7.5, and almost ALL parts are still available including
pistons, and all bearings. This is a one-lunger Techumseh.
Old outboards are fun. (expecially when they run after
rebuild)

A hobby of restoring or playing with motors is fun, personally
rewarding and not to be dissed, even respected. But for practical &
reliable use these are, well, bottom-of-the-barrel motors & were so
even when new. Any 5HP 2-stroke less than 20 yrs old will outpower a
'70's 7.5 Gamefisher & be more reliable to boot - and is available for
the same or much less than the cost & time of hunting up & buying parts
for one. I have my share of small junkers around, too, Gales & such,
but it is wiser to put any effort or even parts into a good-performing
model of motor. The cheapos also use much richer oil mixes, which gets
expensive & dirtier.
