Well the title says it all, trolling along and then it died. Got it apart and found the lower cylinder casing where the spark plug goes in completely blown off the cylinder!! I have a used power head on the bench and was going to make one good motor out of the two. Any tips or things to look out for? I have the manual and have rebuilt many engines before but never a marine engine. Also I was going to order the gasket set as well as new rings, anything else I should order while I am in there?<br />Thanks,<br />Jason
