got a 56 evinrude fleetwin 7.5.... impeller went away while motoring so it ran pretty warm...replaced impeller complete with new housing and all and now I am getting water in number 2 cylinder. checked head and replace head gasket. compression is ok...but still get water in number 2 .. I thought I knew a little about this little engine but I am having trouble figuring this one out. could not see any cracks in cylinder. any thoughts would be appreciated.
