So far, it looks like I've lucked out. The cylinder walls feel and look
as smooth as a baby's bottom. One wall had more oil on it than the
other, indicating it was the one that was misfiring that last day,
August 2nd. The center electrode of the plug from that cylinder looked
like it had recently broken off down near the insulator, so I suspect
that was the reason for the misfiring. I do see the slightest bit of
scuffing, barely discernible, on the bottom of the top cylinder, but who
knows how long that's been there. Both pistons can be rocked back and
forth a bit, indicating at the least worn rings, and probably worn
pistons. But then, I'd expect that after 20 years, even using it for a
week a year, and as you said, they have higher clearances built-in. One
of those pistons is 44 years old.

I'm still thinking new rings and new plugs will restore most of the
power, and I should replace the crankshaft seals simply because they're
rubber too, are also 22 years old, and have been exposed to that heat.

Then again, I also have a '54 10-horse that's never had the crank seals
or piston rings replaced, and it runs like a scared cat. That's the
motor that normally runs our second boat. Seeing as I've had that one
for 10 years, maybe it would be a good idea to replace that impeller
while I'm in the process of ordering parts, too. :^)

If anything else, scrounge around on ebay. there's still OEM parts
available for those engines if you know what to look for. *Some at
very reasonable prices, too!

Yeah, I watch from time to time. I have to get this motor in good shape
for next year's trip. I have to get this lady out to where she can get
more fish!

You can see the '54 10-horse over the fish's dorsal fin. The 9.5 is
hidden by her shoulder.

Very nice pic! I lived with my aunt and uncle, and she used to sit on
the creek bank and catch these small fish we called chubs, and give
them to the cats!
