I'm buying a used boat with GM 350 gas engines. Any suggestions on
which fuel to use, regular or premium unleaded? Any thoughts on using
after market gas additives?

You aren't going to get any significant performance advantage with
higher grades of gasoline, so regular is the way to go. Not to
mention cheaper.

As to additives, for regular use, the new Sta-Bil - I add it every
time I gas up. The new Sta-Bil formulation has an ethanol stabilizer
in it (I think ithey came to an agreement with E-Zorb) and while phase
seperation hasn't been the problem it was predicted to be, water in
gas can be a problem - I'd use the Sta-Bil at every fill or when you
add gas. I add it to everything here from the two stroke garden stuff
to the lawn tractor.

As to other additives, don't waste the money.

Depends on the age. Some of the older 350s, 60s and 70s, had fairly high
compression and may benefit from premium.

Ran some Lucas Gas Treatment through mine one time to clean it out....
You CAN use Premium....but like the others said...no real advantage
other than it does burn cleaner.

Grades of gasoline are rated by their resistance to detonation.

That's it.

If your boat pings and knocks when running regular, try running
premium. If it runs fine on regular, use it.

I pull a 2800lb boat/trailer combo with an '89 toyota pickup truck.
The truck has a 22RE 4cyl and and A43 4speed automatic transmission.
The trailer has surge brakes. I put in an three row radiator and a
transmission cooler. When I pull the boat, I make sure to run
premium. It pings and rattles like mad, on regular. No nasty noise
when I run premium. She runs fine on 87 octane when not pulling a big
load. Travel on flat roads is not a problem. Climbing hills takes
time.

Here is the link to wiki for octane ratings -

http://en.wikipedia.org/wiki/Octane_rating

Run premium if you NEED to. Save your money if you don't. Buying a
higher octane rating than you need is a waste of money.

Google is your friend. More than you will ever need to know is on the
'net.

Phase seperation hasn't been a problem, you can't be serious. Their's
been many an engine, outboards even more so, that have had all kinds
of problems, and phase seperation has been identified as one of the
biggest problems. Check with BoatUS, ethanol has been nothing but a
problem. If we're luck they will keep it out of marine diesel.
