Outboard engines use several interconnected systems. Select your manufacturer above to browse the exact categories available for your engine, including the following common repair and maintenance areas.

Common Outboard Problems and Where to Start

• Engine overheating: inspect the water pump, impeller, thermostat, pressure-control components, cooling passages, and engine anodes.
• Hard starting or rough idle: check fuel delivery, carburetor or injector operation, spark plugs, ignition components, filters, and intake sealing.
• Weak spark or no spark: test ignition coils, stators, switch boxes or ignition modules, sensors, wiring, grounds, and related electrical components.
• Low compression or poor power: inspect pistons, rings, cylinder condition, head and powerhead gaskets, bearings, and other internal engine components.
• Milky gear lube: inspect prop shaft, driveshaft, shift shaft, bearing carrier, and other lower unit seals for water intrusion.
