What Yamaha 67F-W4599-00-00 Is Used For

Yamaha 67F-W4599-00-00 is a propeller nut kit used on compatible Yamaha outboards where this exact part number is specified. Propeller nut hardware helps secure the propeller assembly and keep the propeller properly installed on the prop shaft.

Replace or order this Yamaha prop nut kit when:

• The original prop nut is damaged
• The prop nut is missing
• The propeller is being replaced
• The cotter pin or locking hardware is worn
• The existing propeller hardware is corroded
• A Yamaha parts diagram lists 67F-W4599-00-00

Because propeller hardware is safety-critical, do not reuse damaged, heavily corroded, or questionable hardware.

Why the Yamaha Prop Nut Matters

The Yamaha prop nut is a small part, but it plays an important role in keeping the propeller secured to the propeller shaft. If the prop nut or related locking hardware is worn, loose, missing, or installed incorrectly, the propeller assembly may not stay properly secured.

A properly matched Yamaha propeller nut kit helps support:

• Secure propeller installation
• Correct propeller hardware fitment
• Safe propeller operation
• Reduced risk of loose hardware
• Proper lower-unit service
• Easier propeller replacement
• OEM-style part matching by number

Always confirm the correct Yamaha prop nut before reinstalling or replacing a propeller.

How to Confirm This Yamaha Prop Nut Kit Fits

Confirm fitment before ordering Yamaha Propeller Nut Kit 67F-W4599-00-00. Propeller hardware can vary by engine model, shaft size, gearcase, propeller style, and production range.

Before buying, check:

• Yamaha outboard model
• Engine horsepower
• Serial number or production range
• Existing propeller hardware
• Current propeller type
• Gearcase size
• Propeller shaft setup
• Yamaha parts diagram
• Whether 67F-W4599-00-00 is listed for your engine
• Whether related washers, spacers, cotter pins, or hubs are also needed

If your parts diagram lists 67F-W4599-00-00, this is the correct PDP to review.

When to Replace a Yamaha Prop Nut

Replace a Yamaha prop nut or propeller nut kit when the existing hardware is damaged, missing, worn, corroded, or no longer secures the propeller properly. It is also smart to inspect the prop nut whenever the propeller is removed.

Common reasons to replace Yamaha propeller hardware include:

• Damaged prop nut threads
• Missing or bent cotter pin
• Corroded hardware
• Loose propeller assembly
• Propeller replacement
• Lower-unit service
• Impact with debris, sand, or rocks
• Worn washers or spacers
• Old hardware that has been reused multiple times

Never reinstall a cotter pin or locking part that is bent, cracked, weakened, or no longer holds securely.

Basic Yamaha Prop Nut Replacement Steps

Always follow Yamaha service guidance for your specific outboard. In general, propeller nut replacement is done during propeller removal, inspection, or installation.

Basic process:

1. Turn off the engine and remove the safety lanyard.
2. Shift the engine into neutral.
3. Remove the cotter pin or locking hardware.
4. Remove the old propeller nut.
5. Slide off the propeller if inspection is needed.
6. Inspect the propeller shaft for fishing line, corrosion, or damage.
7. Clean and lightly grease the propeller shaft.
8. Reinstall the propeller and correct hardware.
9. Install the Yamaha prop nut.
10. Tighten according to Yamaha service guidance.
11. Install a new cotter pin or locking hardware where required.
12. Confirm the propeller spins freely and is securely installed.

Do not force the prop nut onto damaged threads. If the nut does not thread smoothly, inspect the propeller shaft and hardware before continuing.

Yamaha Prop Nut and Propeller Service Tips

When servicing a Yamaha propeller, inspect more than the nut itself. The full propeller assembly should be checked for wear, corrosion, missing hardware, and signs of impact.

During propeller service, inspect:

• Propeller blades
• Propeller hub
• Propeller shaft
• Thrust washer
• Spacer
• Prop nut
• Cotter pin
• Fishing line behind the propeller
• Lower-unit seals
• Gear lube condition if service is due

If fishing line is wrapped around the propeller shaft, remove it and inspect the seal area before reinstalling the propeller.
