It sat for a couple years. The transom wood on the pontoon is questionable. I’ve pulled it and will get one made. Pulled th plugs on the engine to do a compression test antbyhey were rusty. Not good. Engine isn’t locked but wondering if the crank and bearings are compromised. So.

On goes the 115. That’s the max the pontoon is rated For anyhow...


What was the compression? If the cylinder walls are rusty, it will be
low. A shot of oil in there will bring it up temporarily. After a
while the rings may even hone them down enough to be serviceable
again. It is actually pretty amazing how bad those old 2 strokers can
be and still run OK. My neighbor gets "dead" ones all the time and
breathes life back into them. This guy has a fleet of boats that Harry
could only imagine and he got them all free or very cheap.

I suppose you might want to go with the 115 if it is a better motor
tho. What is the weight difference?
