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.

Pro Marine Aftermarket Yamaha Lower Unit Components
Pro Marine 30-Inch Driveshaft – Yamaha F250 and LF250 250 HP 4-Stroke Outboards
The Pro Marine 6P2-45501-11 Driveshaft is an aftermarket replacement lower unit driveshaft for select Yamaha F250 and LF250 250 HP V6 4-stroke outboards.
Designed for the 30-inch outboard shaft configuration, this driveshaft cross references Yamaha OEM part numbers 6P2-45501-10-00 and 6P2-45501-11-00.
The driveshaft transfers rotational power from the engine to the lower unit gearcase, allowing the gear assembly to drive the propeller. It is an essential component of the outboard's drivetrain.
This replacement is listed for select F250 standard-rotation and LF250 counter-rotation outboard applications, including the BTUR, BTXR, TUR, TXR, UA, and XA model families.
Important: Verify the original Yamaha driveshaft part number, engine model, and 30-inch shaft configuration before ordering. Not every Yamaha F250 or LF250 uses the same driveshaft.

OEM and Cross Reference Numbers
Pro Marine 6P2-45501-11 is an aftermarket replacement driveshaft associated with the following Yamaha OEM part numbers.
| Brand | Part Number | Description |
|---|---|---|
| Pro Marine | 6P2-45501-11 | Aftermarket 30-Inch Application Driveshaft |
| Yamaha OEM | 6P2-45501-10-00 | Yamaha Driveshaft Cross Reference |
| Yamaha OEM | 6P2-45501-11-00 | Yamaha Driveshaft Cross Reference |
What This Part Is Used For
The driveshaft is a major component of the Yamaha outboard lower unit. It transfers rotational power from the engine's crankshaft to the lower unit gear assembly.
As the engine operates, the driveshaft rotates the pinion gear inside the gearcase. The lower unit gears then transfer power to the propeller shaft, producing propulsion.
A damaged driveshaft can prevent proper power transfer and may contribute to additional gearcase damage.
Common Applications
- Yamaha F250 250 HP 4-stroke lower unit repairs
- Yamaha LF250 counter-rotation lower unit repairs
- Replacement of damaged driveshafts
- Lower unit and gearcase rebuilding
- Drivetrain repairs following lower unit damage
- Replacement of driveshafts with worn or damaged splines
- Repair of corrosion-damaged driveshafts
- Restoration of damaged lower unit drivetrain components
Important Driveshaft Fitment Note
This driveshaft is intended for select Yamaha F250 and LF250 250 HP V6 4-stroke outboards with the specified 30-inch shaft configuration.
Yamaha manufactured multiple lower unit and driveshaft configurations within the F250 and LF250 engine families.
The 30-inch designation identifies the outboard's shaft configuration and should not be interpreted as the overall physical length of the loose driveshaft.
Do not select a replacement driveshaft based on horsepower alone.
Confirm that the original Yamaha driveshaft matches 6P2-45501-10-00 or 6P2-45501-11-00.
Always verify the exact engine model, model year, shaft configuration, and OEM lower unit parts diagram before ordering.
Compatible Yamaha Outboard Applications
Pro Marine 6P2-45501-11 is listed for select Yamaha F250 and LF250 250 HP V6 4-stroke outboards.
The supplied fitment includes both standard-rotation and counter-rotation lower unit applications.

Common Symptoms and Replacement Reasons
A Yamaha lower unit driveshaft may require replacement due to damage, corrosion, wear, or problems discovered during gearcase service.
Common Reasons for Driveshaft Replacement
- Worn or damaged driveshaft splines

Recommended Installation Practices
- Confirm the original Yamaha OEM driveshaft part number.
- Verify the exact engine model and 30-inch shaft configuration.
