Hi All, I'm posting in regards to a problem my father in law is having. He bought a used 1990 Four Winns 150. Its just a little 15' v-bottom figerglass boat, but it is in good shape. When he thottles up the boat leans to the left really bad, almost the type of lean you would get when you make a sharp left turn. He can hold it straight though. We tried adjusted the trim tab to the max in both ways and it didn't help at all. There is no excessive weight on the left side, because it does this when it is just him in the boat. If you see him coming down the lake, it leans so bad that it looks like there would be 10 people sitting on the left side of the boat. Any ideas as to what could cause this problem? It has a 50hp Johnson outboard on it. To me, it acts like the motor was improperly mounted to one side or the other of the v-bottom to cause it to pull and lean so bad to the left. Thanks.
