pls see below.

Still, 20 years is A LOT for a boat engine (especially if it's not
diesel). At least the engine would need a rebuild if it's not done
already? 414 hours means not very regular use, so there might be some
problems anyway due to long periods of non use?

he used it during summer months and put it in dry storage yard the rest
of the year. he said there were a couple of years of non use because
of new child.

he also redid the floor and stringer 2 years ago (the wood
was treated with fiberglass).

A new floor can hide lots of problems underneath. Is there any way to
tell? Any inspection hatches or can you measure moisture (when the boat
has been out of water)?

any tell tale signs I should beware of besides obvious rots?

Maybe he wants to sell the boat because there's problems under the
floor, or maybe he doesn't want to pay for the engine rebuild. Or maybe
it's just getting too old/small/whatever for him...

He just got a newer bigger boat.

Does the seller seem a very trustworthy person?

he seems to be quite honest. btw, his final price is $3k.

thanks.
