VIF Propeller Installation Hardware Kit for Yamaha 60–85 hp, 15-Spline Prop Shaft — Thrust Washer, Spacer, Washer, Nut & Cotter Pin

VIF propeller installation hardware kit supplies the thrust washer, spacer, washer, nut and cotter pin needed to mount 15-spline propellers on Yamaha 60–85hp outboard motors (Ref No. 688-45987-01).

This aftermarket hardware kit is engineered to replace the small but essential parts used when installing or servicing propellers on compatible Yamaha outboards. Each kit is sold as pictured and includes all the fasteners required to secure a 15-spline propeller to engines in the 60 to 85 horsepower range. The components are produced under quality control processes to ensure fitment and reliability for routine maintenance and repairs.

How do I know this kit fits my Yamaha outboard?

Fitment depends on spline count and engine model. This kit is intended for Yamaha outboards rated 60–85 hp that use a 15-tooth propeller shaft and correspond to Ref No. 688-45987-01. Always verify your engine serial number and propeller spline count before ordering.

• Designed for 15-spline prop shafts (count the teeth on the propeller hub)
• Intended for Yamaha 60–85 horsepower outboard models
• Reference part number: 688-45987-01 to confirm compatibility
• Check your owner's manual or the stamped numbers on the lower unit for model confirmation

What parts are included and what are they for?

The kit includes a thrust washer, spacer, flat washer, prop nut and cotter pin—everything needed to secure the propeller to the shaft. Each part serves a simple mechanical role: spacing, bearing surface, locking and retaining the propeller in position during operation.

• Thrust washer — provides a bearing surface between prop and hub
• Spacer — corrects axial clearance on the shaft
• Flat washer — even load distribution under the nut
• Prop nut and cotter pin — secure the assembly and prevent loosening

How does aftermarket quality compare to original parts?

Aftermarket kits like this one aim to match OEM fit and function while offering a cost-effective replacement. VIF states the components are manufactured under strict quality control; however, inspect parts for finish and dimensions during installation to ensure proper seating and torque specifications are met.

• Manufactured to fit the specified Yamaha spline and shaft dimensions
• Quality control checks applied during production for consistent parts
• Sold as shown — inspect visually before installation
• Contact seller for questions or multilingual support (English or Spanish)

Can I install this kit myself, or should I see a mechanic?

Installing propeller hardware is a straightforward mechanical task for anyone comfortable with basic tools, torque specifications and safety steps. If you’re unsure about torque values, shaft condition or pinning the cotter pin correctly, a marine mechanic or dealer installation is recommended.

• Requires common hand tools and knowledge of propeller torque and safety
• Inspect shaft threads and splines for wear before assembly
• Follow manufacturer torque and cotter pin routing recommendations
• Professional installation reduces risk if you’re inexperienced

Who is this for: This VIF hardware kit is suited for boat owners, DIY marine technicians and service shops that need a complete set of propeller fasteners for Yamaha 60–85 hp outboards with 15-spline shafts. It’s useful for scheduled prop maintenance, seasonal winterization, emergency replacements at the dock, or when upgrading/changing propellers. If you need fit verification or assistance, contact the seller with your engine model and serial number to ensure correct selection.
