Exhaust hull fitting 2467 Side lead-through A side lead-through is installed on the side of the boat or in the transom. In sailboats, it is recommended to install it in the transom. The installation always requires a so-called goose neck piece. Make the necessary installation cut-outs and spread a suitable sealing agent on both sides of the seal and on the screw holes. This will ensure that the connection is waterproof.
