A Sea-Doo crankshaft is a mechanical component found in the engine of a Sea-Doo watercraft that converts linear motion from the pistons into rotational motion. It consists of a series of rods, or crankpins, that are attached to the ends of the pistons and connect to a central shaft. As the pistons move up and down in the cylinders, the crankpins rotate the crankshaft, which in turn drives the output shaft and powers the Sea-Doo.

Sea-Doo crankshafts are typically made from high-strength materials such as steel or aluminum alloy, and are designed to handle the high levels of stress and wear that are common in marine environments. They are usually supported by a series of bearings that allow them to rotate smoothly, and may also be equipped with seals and other protective measures to prevent water and debris from entering the engine.
