Hello members. So I buy this boat, motor and trailer knowing there was a issue with the motor. A very clean looking 1989 Force 50 hp. The price didn't include any cost for the motor. The previous owner said he was told the something about a piston pin. I didn't care or even look at the motor per say. Even if it ran perfect I wouldn't want it due to 25 hp restricted lake. I get it home and pull the cowl. The head was attached by one bolt. I pull it and see two things. I tried posting pics but can't figure it out because I can't put a wrench on it. First thing that caught my eye was the bottom piston and head chamber were clean. Espically in one specific area. My thought was a blown head gasket. Then I see two perfect gouges on the very bottom of the cylinder. Right between the two ports. Possibly matching his explantion of the piston pin . So then I emailed him some questions. He said the motor started running rough with no power. Dosen't remember any noise. I think there may have been a issue going on with the piston pin he didn't know about. Then the head gasket blows. He takes it in and is told about the piston pin. Question! What would cause the pin to drop and cut into the cylinder. Unless it was made that way. The motor turns over by hand fine and feels fine on the strokes. I ordered a new gasket to put it back togeather and see what happens.
