CRITICAL: DO NOT START THE ENGINE

Do not crank or start the engine. Water in the cylinders will hydrolock it and bend internals on the first revolution.

Swamped Engine Recovery

A following sea over the transom, a swamped cockpit, or a boat that has part-filled at the mooring can all push water into the engine through the exhaust or intake. Water does not compress — if it has reached the cylinders, a single crank can bend a connecting rod. The right move is to keep the engine off and get a marine technician to it before any damage is locked in.
