Re: Water in the # 2 spark plug
As was said, it could be a result of a number of things. So... you've got to work with what you've got ( Ideally, you would have pulled the distributor and spun the oil pump to distribute some oil to the bearings and the cylinders before you tried to start the engine, but it's too late for that now.) So, leave the plugs out; squirt some oil in each of the cylinders; spin the starter to distribute the oil. Connect the earmuffs to the outdrive and spin the starter, without the plugs. See if water comes into the engine. If so, you got either a manifold crack/rust-through, a lown head gasket, or a cracked block/head. Then you'll have to tear everything aprt to check it out. If no water shows up, put the plugs back in and try to start the motor. Since the boat was, as you said, covered for fifteen months, I do think rain water is unlikely, but hopefully I'm wrong. More likely, however, it's a manifold, head, or block problem. Let us know what you find. Good luck. Hy
