Just picked up an 05 Larson with a Mercruiser 5.0 . Wanting to change over to through hull exhaust and have some questions . Looks like all I have to do is unbolt the tube that goes from the risers to the y pipe and block off the y pipe . Then drill some holes in the transom and connect the new fittings . What im wondering though is about the distance between the risers and the new exhaust tips that will be mounted in the transom . It will be about a foot between this connection . Is there some kind of high heat tubing I can run between here or will I need a splice piece of stainless ?
