Motorboat mechanics maintain and repair boat motors.

Motorboat mechanics inspect boat motors for signs of mechanical, fuel, or electrical problems. They may use computerized testing equipment.

Motorboat mechanics make repairs after locating a problem. They may refer to service manuals for information. Some repairs and routine maintenance are simple. Other repairs require taking the engine apart using hand tools. They may repair or rework parts before putting them back in engines. Mechanics repair parts using:

• Lathes
• Drills
• Grinders

Mechanics reassemble the engine after repairing or replacing faulty parts.

Motorboat mechanics adjust the carburetor mixture and timing. They make adjustments to generators and test the cooling system. They examine propellers and propeller shafts. Mechanics set starter locks and align steering and throttle controls.

Outboard motors are remounted to the boat after all repairs and adjustments have been completed. Mechanics operate boats at various speeds to make sure they are running smoothly.

Mechanics write reports after finishing repairs. This report lists the work performed on the engine and its general condition.

Motorboat mechanics service and maintain portable outboard motors in the repair shop. They work on inboard motors at the dock or marina. Inboard motors are removed from the boat only when a major overhaul is required.
