The gentlemen I bought from was a service manager at a marina in Burlington on Lake Champlain. He bought it with something different then the merc. But they didn't winterize it right and cracked the block. So he bought a boat that hit some rock's or ledges with the mercruiser motor and out drive. He told me it only had 60 hours on the merc. Then he had to redo the transom so merc out drive would work. The did a very nice job on that and also rewired everything.
