Mechanic inspects saltwater-damaged engine aboard wooden cruiser
What this video covers
A 4-cylinder Yanmar diesel engine on a cruising sailboat suffered water intrusion after a deck drainage line became obstructed by debris.▶ 14:05 The blockage caused water to back up through an anti-siphon loop and into the engine cylinders.▶ 17:06 Upon discovery, the owners found the engine would not turn over and observed water exiting the exhaust system.▶ 5:28 A mechanic disassembled the engine to inspect for internal damage, specifically checking for bent connecting rods.▶ 8:42 While the cylinders showed minor surface corrosion from the water exposure, the internal components remained intact and the engine did not require removal from the vessel.▶ 11:09 The mechanic cleaned the cylinders and treated them with oil to prevent further degradation.▶ 11:22 The owners plan to install a plug in the deck drain during future storage periods to prevent similar blockages from leaves or debris.▶ 22:00 The incident highlights the importance of maintaining clear deck drainage paths to protect the engine's anti-siphon system.▶ 22:00
