I acquired a 1971 Tri Sonic, Tri-Hall Open Bow. It has a Mercuiser
165hp inline Chevy 6, in very good condition garaged most of its
life and well cared for.
I was hoping to find a group or information on this type of boat
or at least the power train. Currently after adding a new
manifold, tune up, re surfacing
the head and oil change she purrs like a kitten. We took her out
on our 1st break in cruise, just such a pleasant experience. I
have had many boats in my
day, even sunk a couple. I never had a boat run like this on its
1st cruise especially one this old. But when I pulled into the
dock and shut her down to
unload, I tried to start her back up to move her to the boat
trailer and the starter just spun. Sounds like the the starter
would not engage, just this
winding noise, like something spinning in the starter. I don't
know what might have caused that since the starter looks like new.

Thank You in advance for anyone that can shed some light on this.

You might want to ask this question on "rec.boats" instead of
"rec.boats.cruising" there are some knowledgable engine guys over
there if you can attract their attention. Just ignore the
political
and personal BS. It sounds to me like the starter gear (sometimes
called a Bendix) is not engaging properly and it may need to be
replaced or rebuilt.

Back in the '60s when I was involved in the design of heavy duty
cranking motors for the over the road diesel fleets, the Bendix
salesman
told me it was common practice to pull the cranking motor complete
with
Bendix drive assembled, and stick it in a gallon bucket of kerosene
for a
few days to free up a stuck drive.

These days, can you still buy kerosene in bulk?
