There is a couple ways to do this. There is the easy way and a hard way. The easy one is to redrill new holes and turn the motor about 25 degrees. It will put the pipe out the cowling. Im not a super tirge man. So the hard way would be for me to tell you what parts for you buy. If you redrill hole find some wood to expoy in the old holes. Its not as hard as it sounds. it might take a hour or two to redo .
