My dad bought a '92 overnighter that wasn't winterized and has a bad block (he pulled the heads and verified it is trash)...He has been an Auto mechanic his entire life so no worries on anything basic or similar to cars/trucks...but he isn't quite sure about what is required to remove the engine from this boat. his primary question is whether or not the drive has to be removed from the boat or can the engine simply be unbolted in the back and taken out? I have a large skid steer so maneuvering it around is not problem. also, any specialty tool required for the job? Any other useful tips/tricks for this process? He is searching for the correct long block now and i believe they want the damaged block for core charge so it will be coming out soon. PS: He is probably going with Jasper engines as he has had good luck with them in the past with his shop and trusts their warranty.
