"my yamaha is leaking oil, but

"my yamaha is leaking oil, but it looks like a milk shake probably with water too and smells to gas also , it seams to be from the lower crank shaft oil seal , first I thought it was from the oil pump, but after remuving the oil pump , still happend the same , so I think it have to be from the lower seal ..the motor runs fine , and it has good compression 110psi in the lower piston and 115psi in the other two ..It's that possible ? thanks in advance."

", find that water is getting into the cylinder, remuved the head and after pushing the cylinder saw sings of water in the intake whre the gas get into the cylinder. I think that the block is crack around the cylinder, the compression is good 120 psi ..there is any way to seal a block in an outboart..is a yamaha 1989 90hp"
