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.
- Lower unit or gearcase noise: inspect bearings, gears, clutch components, shafts, and gear lube condition before continued operation.

Pro Marine carries both genuine OEM parts and quality aftermarket replacement parts for many outboard maintenance, repair, and rebuild applications. Always confirm fitment using the engine model, serial number, horsepower, year range, or OEM part number when available.
Frequently Asked Questions
How do I find the correct parts for my outboard motor?
Start by identifying the engine manufacturer, horsepower, model number, serial number, and year. Select the manufacturer above to browse by engine system, or use the OEM parts lookup to locate the original part number from a factory diagram.
Can I search Pro Marine by OEM part number?
Yes. If you already have the OEM part number, enter it into the Pro Marine site search to locate available OEM and aftermarket replacement options. If you do not know the part number, use the OEM parts lookup first.
What information should I have before ordering an outboard part?
Have the engine manufacturer, horsepower, model number, serial number, and year whenever possible. An OEM part number from the original component or parts diagram is especially helpful because visually similar parts may fit different engine families.
What is the difference between OEM and aftermarket outboard parts?
OEM parts come from the original engine manufacturer. Aftermarket parts are replacement components manufactured by other marine parts companies for compatible applications. Pro Marine carries both OEM and aftermarket options across many common outboard engine systems.
Are aftermarket outboard motor parts reliable?
Quality aftermarket marine parts are commonly used for maintenance, professional repair, and engine rebuilding. The best option depends on the application, manufacturer, availability, and customer preference.
Do you carry parts for older outboard motors?
Yes. Pro Marine carries parts for many older Mercury, Mariner, Johnson, Evinrude, Chrysler, Force, Yamaha, Honda, Suzuki, Nissan, and Tohatsu outboards. Availability varies by engine family and component.
What outboard parts are commonly replaced during routine maintenance?
Common maintenance items include engine oil, oil filters, fuel filters, spark plugs, water pump impellers, complete water pump kits, thermostats, gear lube, drain plug seals, anodes, and manufacturer-specific service kit components.
Fitment Tip: Outboard parts can vary by model, serial range, horsepower, and production year. Confirm the OEM part number or engine identification information whenever possible before ordering.

Do not order a cylinder head gasket by horsepower alone.
For Yamaha applications, verify the complete model and confirm the engine calls for one of the 67F-11181 gasket numbers listed above.
For Mercury applications, verify the complete engine serial number and confirm the gasket cross references 804115 or 8041151.
OEM & Complete Gasket Kit Options
Pro Marine also stocks the genuine Yamaha OEM version of this head gasket, as well as a complete powerhead gasket kit for compatible engines.
Genuine Yamaha OEM Cylinder Head Gasket - 67111-1
Genuine Yamaha factory version for compatible applications using the 67F-11181 cylinder head gasket family.
Choose this option when an OEM Yamaha gasket is preferred for the repair.
Pro Marine Powerhead Gasket Kit - 6803
Performing a complete powerhead rebuild? The 6803 gasket kit is the better starting point when multiple engine gaskets and sealing components will be disturbed.
What This Cylinder Head Gasket Does
The cylinder head gasket seals the joint between the cylinder head and engine block. It helps contain combustion pressure while sealing the cooling and lubrication passages that pass between the two components.
Proper sealing is critical for maintaining compression and preventing cooling water, combustion gases or engine oil from moving between passages where they do not belong.
Common Signs of Head Gasket Failure
- Low or uneven cylinder compression
- Cooling-water intrusion into one or more cylinders
- Overheating
- Combustion pressure entering the cooling system
- Visible erosion or failure of the old gasket
- Corrosion around the combustion sealing area
- Evidence of leakage between adjacent passages
What to Inspect During Cylinder Head Service
Whenever the cylinder head is removed, inspect the head and block sealing surfaces for corrosion, erosion, pitting, distortion and other damage that could prevent the replacement gasket from sealing correctly.
The applicable Yamaha or Mercury service manual should be followed for surface inspection, tightening sequence, fastener requirements and torque specifications.
Individual Head Gasket vs. Complete Powerhead Gasket Kit
| Type of Repair | Recommended Option |
|---|---|
| Replacing only the cylinder head gasket | Pro Marine 67111 is a cost-effective individual replacement. |
| OEM gasket preferred | Choose the genuine Yamaha OEM 67111-1 gasket linked above. |
