I am looking at a used engine Evinrude 115hp (1995).The owner has said that the base gasket has failed and water has entered through the exhaust port into the bottom cylinder. Engine turns over freely and the compressions are all the same as this test Compressions are No1 120psi No2 120psi no3 115 psi no4 110 psi.
Is this a difficult problem to fix?
