I am considering buying a 97 starcraft 1810ss it has a 4.3 mercruiser alpha 1 owner claims that it has a cracked block and water was in the oil . question is what else should I be looking for I am assuming the cracked block was because of not being winterized what other damage can there be. the interior is dirty with a little cracking because it has been sitting outside uncovered. Is it worth the risk to buy this boat and rebuild it or am I better off moving on and getting a boat that is water ready.
