1993 mercury 175 xri problems

[jtpettis]

hey guys i am new to this site although i have found some useful info on this motor on here. the problem i am having is that i am having water entering one of the cylinders. from the research i have done it sounds like a blown head gasket. i have replaced the fuel water seperator and have run probally 75 gallons or more of fuel through it and it is still there. any help would be appericated.

75 more gallons and it was a known leak into a cylinder???i bet its in fine shape. which cylinder

[jtpettis]

it is on number 5 cylinder and i have taken the plug out of it and let it dry out completly then hooked up to the hose run for about 10 minutes and there is water droplets only on the one plug again it also has a bogging problem coming out of the hole i am unsure wether it is fuel system or could be assoiated with possibly a head gasket

[flabum1017]

either a head gasket, porous head or divider plate gasket other less likey things such as a cracked block, water ingestion etc..........
