The 35 hours figure comes from a digital read from the engine. Based
on the condition of the boat, I believe it. Its been stored in dry
dock and in excellent condition.
Why didn't I question it? I'm an idiot, I guess - and I didn't note
anything from the sea trial.
My question is... what are the common causes of low compression, how
much $ to fix, and is it something that I need to address right away?

thanks

Sorry if I came across the wrong way. I only wanted to express my view that
35 hours on a 3+ year old boat is suspicious.

Low compression normally comes from cylinder wear, something occurring over
time. The fix in that case is rebuilding the engine (reboring the cylinders
to a slightly larger diameter and putting in larger pistons), something that
can normally be done only once on an engine.

With only one bad cylinder and with the low hours you report the problem, as
Netsock previously suggested the problem is likely to be with a piston ring
in cylinder #1.

#1 cylinder gives a hint that maybe some water got into that cylinder and
sat, causing some corrosion. I'd run it, check the oil condition frequently,
and hope, if the corrosion isn't too bad, that it gets better after running
it for a few hours.
