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.

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.

Yamaha F250 – 250 HP 4-Stroke

Yamaha LF250 – 250 HP Counter-Rotation 4-Stroke

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
• Corrosion or pitting on driveshaft surfaces
• Bent or twisted driveshaft
• Damage following propeller or lower unit impact
• Excessive wear discovered during gearcase rebuilding
• Damaged driveshaft bearing surfaces
• Internal lower unit drivetrain damage
• Replacement during a complete lower unit rebuild

Unusual drivetrain noise, vibration, or loss of propulsion may indicate a lower unit problem, but these symptoms are not specific to the driveshaft. Inspect the complete gearcase to identify the cause.

Installation and Service Tips

Driveshaft replacement requires proper lower unit disassembly, component inspection, and reassembly using the appropriate Yamaha service procedures.

Recommended Installation Practices

• Confirm the original Yamaha OEM driveshaft part number.
• Verify the exact engine model and 30-inch shaft configuration.
• Inspect the existing driveshaft for spline wear, bending, twisting, and corrosion.
• Inspect the mating crankshaft and pinion gear splines for damage.
• Check driveshaft bearings, seals, and related gearcase components.
• Inspect the lower unit for water intrusion or internal corrosion.
• Follow the appropriate Yamaha service manual for gearcase disassembly and reassembly.
• Use the specified lubricants, tools, and assembly procedures.
• Verify proper lower unit operation before returning the outboard to service.
