gms are known for having heat related problems with the starters so perhaps
you did damage it when you overheated. Or you damaged the starter trying to
turn over the overheated motor. When a motor overheats the piston rings can
over expand and temporarily seize in the cylinders. When you say you can
turn it over by hand, you mean you can put a breaker bar on the crankshaft
front bolt and turn the crank? Cause just turning the waterpump pully ain't
the same thing.

If you're trying to save money pull the starter and see if it is locked up.
The ends come off and it has bearings in either end. Replacable too if
you're handy at that sort of thing. You can also spin it off the motor with
a jumper cable. It will jump so have someone hang on to it.

I can roll the motor by hand. I had my local mechanic look at it and he
said that since the motor can turn (by hand) he doubt it seized. Then he
checked the amp draw and he said it was off the scale on a 400 scale. He
also checked the voltage drop on the battery (standard battery, not
marine)
and it was approx 1.6 which he said was also high.

My main concern is whether it was coincidence that it overheated then i
couldn't start it (being that the starter went). I could have always
clogged the intake with weeds then coincidence that the starter blew...
but
i don't like relying on coincidence's.

I doubt that it is the starter. Much more likely the motor is seized.

Do you think it could be the starter? Cause I checked the amp draw and
it
was over 400 amps. From what i was told that is a bad starter... but
if
so
would it still crank a little if the starter is completely shot?

Remove the spark plugs and see if it will turn over. If not, remove
the
stern drive and try again.

First boat owner for about a year and a half, I have a 94'
Chaparral
w/
a
Mercruiser I/O (all maintence done at end of last year). I was
recently
in
a local lake and heard a clunk, which i believed turned out to be a
rock.
I
was in a no-wake zone so going very slowly, no physical damaged
noticed.
Don't know if this is related to what I'm about to say but thought
the
background might help anyone come to a conclusion. I noticed about
5
minutes later the temperature alarm went off and temp was climbing.
I
shut
down immediately, then waited about 2-4 mintues and tried to
restart.
As
I
turned the key the engine maybe cranked once or twice then nothing,
waited
some more and same problem. (It was something like when the
battery
dies
and the engine won't turn over completely) But the battery was
charged
fully (I also tried to jump it). I noticed that as i continued to
attempt
to start the boat the cables to from the battery got extremely hot
and
then
one seemed to smoke a little as i was attempting to crank. I
checked
the
battery afterwards (being towed out of the water) and all was fine.

Anyone with any suggestions, is greatly appreciated.

THANKS.

-Matt
