1. Remove the Exhaust Bellows
With drive unit removed from the bell housing, block the bell housing in the full up position and loosen the screws for the two clamps at either end of the exhaust bellows. Access the aft clamp from underneath. To loosen the clamp at the transom housing, insert a quarter-inch extension with a socket wrench through the access hole on the port side of the transom housing. With clamps removed, slit each end of the bellows with a sharp knife (while being careful to avoid damaging other parts) to allow for easy removal.
