I was wanting to know if im over reacting.....I couldn’t get the motor to fire up so i pulled all the plugs out, thinking I had flooded the motor, and turned it over and water started spitting out of all four cylinders what could this be blown heads cracked cylinders. Any help would be nice..<br /><br />Thanks Nathan

First of all, how much water was being discharged out of the cylinders?<br /><br />If it was a small amount out of each cylinder than try checking for water in the fuel that may have gotten into the fuel tank. You can crack a drain screw on one of the carbs, at the front on the float bowl. <br /><br />If there is a lot of water coming out than you may have a blown exhaust cover gasket. This could possibly alow water to enter all four cylinders. Check for water leaking past a screw or screws on the plate at the back of the powerhead, between the two heads.<br /><br />hopefully this helps.

The torque should be twenty foot ponds and done in a couple of stages. First snug them up, then torque to ten foot pounds and then to a final torque of twenty. If you replace the head gaskets this also gives you a chance to have a good look at the cylinders.
