Re: Buying a used boat
If you stingray had a merc 4.3 it is the same block -- same compression check. Both mercs and volvos use the same GM block.
That engine is super clean. That says to me this person really detailed and kept the boat clean. Obviously wiped down the engine too. You could not get it that clean if you waiting just until you wanted to sell it to clean in.
On the outdrive what I think your seeing is exposed aluminum. Ask him about this. Did he use something like CLR to get of calcium deposits and just weaken the paint in that spot? That is the spot on my merc that gets the hottest and get the most calcium deposits on it. Maybe Volvo's are the same. My bet is the guy will be able to tell you about the paint missing there.
Also, when Stingray went all volvo for a couple of years I do remember a few people writing in about the volvo outdrive paint peeling. This could be the case, but I would expect it to peep more broadly across the outdrive, versus just where it has peeled.
Clearly, the guy is not hiding that area of the boat in the add. Give him a shot and ask what is up there.
