"I just purchased a 2001 Chapa

"I just purchased a 2001 Chaparral (180SSE) that has a damaged engine. The previous owner didn't winterize it properly. When he went to change the oil in the spring, the shop pumped out several quarts of water from the crankcase. The boat sat for 3 years before I bought it. The boat only has 18hrs on it. When I got the boat home, first thing I did was install the drain plugs in the block & added about 2 gallons of water into the intake. I checked the oil level prior to adding water, it was @ the full mark on the dip stick. After about 2hrs, I checked the oil level & it had increased about 1qt. This verifies that water is indeed getting into the crankcase, as reported by the previous owner. I have some questions that need answered before commiting to a cracked block. As I was adding the second gallon of water, water began to stream out of the right side of the engine. Couldn't tell exactly where it came from, it seemed to be coming from the exhaust manifold-to-cylinder head attach area. Could there be a crack in the manifold & water seep into the crankcase past the pistons? What should my next step be? Is there a way to verify the block is cracked/scrap without actually pulling the motor & tearing it apart? I got the boat cheap & can purchase a re-man long block, install it & still be way ahead. Don't know much about the history of this 4.3 engine & what is common on engines that have not been winterized properly. Anybody out there with direction?

Thanks"
 
"They normally crack in the wa

"They normally crack in the water-jackets below the pistons and towards the crank-case. Suggest You start looking for a 4.3 long block as crank, bearings etc it probably corroded. Most likely the exhaust manifolds need replacement as well."
 
Thanks for the info. Any hints

Thanks for the info. Any hints-or-tips for pulling the engine? Any special things to look for. Looks fairly simple.....
 
"Lift it out of the boat!

"Lift it out of the boat!
Either by splitting at flywheel, but would recommend to take off the drive and lift complete with flywheel-housing.
Take down oil-pan and 'fill' cooling system with water. This will probably give You a quick idea of where the crack(s) are."
