@blakeyates As others have mentioned, I am confused by your statement. If you took it for a test drive and checked it out before you towed it home, the engine was fine at that time, and it is really tough luck that the very next time it was started there was a failure. That is assuming that nothing in the tear down indicated that something was Mcgivered by the seller. If purchased with no warranty, the seller has no obligation, although if it was something I had sold, I would have a hard time saying no with those circumsances. If it was actually purchased without a test drive and the seller said all was good, then the seller has an obligation. By the way, never, ever, ever buy a used boat without a test drive.
