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.
- Trim or steering problems: inspect hydraulic fluid level, seals, hoses, trim motors, pumps, steering cylinders, and mechanical connections.

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 connecting rod bolt by horsepower alone. Yamaha used multiple connecting rod and rod-bolt designs across these engine families.
Verify your full model designation and confirm 6CB-11654-00-00 before ordering.
What This Part is Used For
The connecting rod bolt secures the connecting rod cap to the connecting rod around the crankshaft journal.
This fastener operates under repeated high tensile and cyclic loads as the piston and connecting rod accelerate and decelerate throughout the engine cycle. Correct fastener condition and installation are critical during a powerhead rebuild.
When Should a Rod Bolt Be Replaced?
Connecting rod bolts should be carefully inspected whenever the connecting rod is removed during engine rebuilding.
Follow the applicable Yamaha service manual for reuse criteria, tightening sequence and torque procedure. If Yamaha specifies replacement after removal for the exact application, install a new bolt rather than reusing the old fastener.
Inspect During Connecting Rod Service
- Connecting rod big-end bore
- Connecting rod cap mating surfaces
- Rod bearing condition
- Crankshaft rod journal condition
- Rod bolt threads
- Rod bolt seating surfaces
- Piston pin and small-end bore
- Piston condition
Powerhead Rebuild Installation Notes
Internal engine fasteners should be installed according to the Yamaha service procedure for the exact model being rebuilt.
Make sure the connecting rod cap remains matched to its original rod and orientation, and verify all crankshaft and connecting rod clearances before final assembly.
Do not substitute a different rod bolt simply because it appears physically similar.
