I might be nervous about "just fitting" in the space .. You might also ask what experience they'd have with your particular saildrive
I had a similar situation with water in the saildrive
lube and it turned out to only the underwater fill screw that was not-quite-tight-enough. You and we (me esp.) should all be so lucky again. All it took was a pressure test to find the problem.
However, about 10 years ago, I was asked to go up to Perth Amboy and oversee a prospective purchaser's survey
of a 57' Swan that I'd captained previously. The yard where I found the boat berthed (Lockwood, I think) had 30 or 35T lifts and while the boat's specs said she was only 25T, I wanted MORE as I suspected much more weight with the Swaw. It was originally a very custom build with many fuel
and water tanks
than the the 'std." plus a centerboard
and a ketch
with add-ons such as custom boomkin/back deck
She just seemed, also, so VERY big for the available lifts. I asked -- and was pointed to a yard at Tottenville.
Afterwards, I gave the yard there the highest marks I could give and wish I knew it now but there can't be many, many along that stretch. This one had a bunch of old broken off at-the-water pilings at the surface and I was given word to avoid them. The workers who came out to haul the Swan were dirty from head
to toe too !! I found nothing to dislike there !
