    the new one is grounded thru the case, connect your trigger wire to the S terminal. looks like old one had 5/16" studs, new one has 3/8" studs? looks like generic bakelite casting. S = Start, I = Ignition. same as a starter relay.

    a waterlogged hull sitting low in the water will allow water to migrate to the cylinders thru the exhaust, and will get into the oil other than that, large quantities of water in the fuel will make it run like crap and may get past the rings at idle. having water spray on the engine may have...
