Just bought a 2000 Starcraft with 3.0 merc with about 50 hours on it. Ran fine but poor idle. Figured year old gas was problem. Changed gas but still the same. Pulled plugs - water on the back plug. Compression test has all 4 cylinders at 150. Back cylinder sprayed water out plug hole when spinning over, No water in oil. I figure possiblity is cracked block, head or exhaust manifold or head gasket. Any one of those more likely given the symptoms.

Thanks Mal
