If I had to take a guess, based on an identical symptom that I had a couple
years back (also on the launch ramp -- as opposed to out on the Lake) --
my bet's on the starter motor. It could also be be solenoid on the starter
or it could also be the remote (slave) starter relay. Thar last relay is, I
believe, interchangeable with the tilt-up and tilt-down relays.

On the starter motor, the originals use the GM Delco 10MT (long/short
mounting bolts) Marine-rated starter which is a 20+ pound hulk of a beast.
They have enough mass to crankover forever without over heating. You can and
probably should get the newer style GM permanent magnet gear reduction
(PMGR) Marine starters. These have higher torque and weigh-in at less than
half the mass. These are readily available from numerous suppliers. Try: They run
about a $115, brand new. Be sure and get it complete with the long/short
mounting bolt kits, as the old bolts will not work. Another double-check is
to insure your Buick V6 uses the pre-86 starter mounting bolt pattern. The
mounting holes on the motors are not staggered, as were later GM enginges.
You could have the old 10MT-beast rebuilt, but in my opinion. it's best
suited to bench pressing in the weight room. Why carry all the weight

I would first make sure the remote (slave) starter relay is not suspect.
That relay runs about $35.00 and it is a good spare to always carry onboard
since the boat uses three of them. The new starter will come complete with
the integral solenoid. I would hate to see you swap the starter and not
check everything else: 1) Battery, 2) cables, 3) control wires from switch,
4) remote relay, and 5) finally the starter. (Oh yeah, And don't forget to
check those Prestolite alternator brushes, while your into the electrical

Anyways look at the bright side --- be glad it happened on the launch ramp
and not in harms way!
