"I have a 1985 mcm470 on a1979
"I have a 1985 mcm470 on a1979 grady white... did alot of work this winter to it..new exhaust manifold, carb,starter coil...etc had some water in the motor from a cracked exhuast manifold, so i replaced it. When i took it for a test run it bogged down after 10 min ( it ran fine on land with ears for 20 min).I pulled the plugs and number 4 was wet. Turned the motor over and had water come out of the cylinder. Waited 10 min turned it over again water again.. Checked the compression of the number 3 and 4 cylinder(150) in both...Could it be a head gasket? The exhaust manifold was still full of coolant??? Any help i would appreciate it...Thank you"
