How to Remove the Flywheel From a Boat

The flywheel is a round-toothed mechanism that rotates and creates energy that helps to power an outboard motor's crankshaft. If repairs are needed on your motor's crankshaft or powerhead, the flywheel has to be removed. Sometimes, the flywheel itself gets damaged, which also requires removal. This job is best done with the help of an assistant to help remove the flywheel.
