VQPROPs Outboard Propeller for Yamaha 13 5/8x13 — 15‑Spline RH, 3‑Blade Aluminum Corrosion‑Resistant

VQPROPs 13 5/8x13 outboard propeller is a 3-blade, right‑hand 15-spline aluminum prop designed to fit Yamaha 60–115HP engines and deliver reliable acceleration and efficient cruising.

This propeller is engineered as a direct-replacement option for many Yamaha outboards in the 60–115 horsepower range. Built from corrosion-resistant aluminum with a patented anti-corrosion finish, the prop balances durability with lightweight performance. Before ordering, confirm diameter, pitch, spline count, and rotation to ensure a proper match with your boat and gearbox.

How will this prop affect my boat's speed and acceleration?

The 3-blade 13 5/8x13 design focuses on a compromise between top speed and quick throttle response. Its blade area supports good bite in the water for firm acceleration while maintaining efficient cruise RPMs. Expect a noticeable improvement over worn or mismatched props when correctly selected.

• Tighter hole-saw pitch for quicker hole shots and planing.
• Aluminum construction keeps rotational weight low for snappier throttle response.
• 3-blade layout balances speed and load-carrying capability.
• Optimized for Yamaha 60–115HP powerbands when matched to engine gearing.

Will this prop fit my Yamaha engine and how do I check compatibility?

This prop is made with a right-hand (clockwise) rotation and a 15-spline hub to match specific Yamaha lower units. Fitments commonly cover Yamaha motors between roughly 60 and 115 horsepower, but fit depends on diameter, pitch, spline count and rotation. Always compare the new prop’s specs to your existing propeller before ordering.

• Confirm 15 spline tooth count on your prop shaft.
• Verify right-hand rotation matches your engine model.
• Compare diameter (13 5/8") and pitch (13) to your current propeller.
• Check propeller part numbers or owner’s manual for exact fit guidance.

What materials and protections does this propeller use to resist corrosion?

The propeller is cast from marine-grade aluminum and finished with a patented anti-corrosion coating to extend service life in salt and freshwater environments. That protective layer helps reduce surface corrosion and pitting that commonly occur with prolonged exposure to water. Regular inspection and maintenance will help preserve performance and appearance.

• Marine-grade aluminum core for strength and lower rotational mass.
• Patented anti-corrosion coating to limit saltwater damage.
• White finish that aids visual inspection for nicks and wear.
• Easy to clean and touch up between maintenance intervals.

How easy is installation and what service support is provided?

The propeller is supplied as pictured and installs like a standard Yamaha replacement unit—remove the retaining nut and slide the hub assembly onto the spline, observing thrust washer alignment. VQPROPs provides customer support and accepts returns within the specified policy window if the propeller does not match your needs.

• Sold complete and ready to fit; no additional parts included unless specified.
• Installation follows standard Yamaha prop removal/installation steps.
• Customer support available for fitment questions; returns accepted per policy.
• Inspect hub, nut, and cotter pin condition when fitting to ensure safe operation.

Who is this for: This VQPROPs 13 5/8x13 3‑blade prop is intended for boat owners with Yamaha outboards in the roughly 60–115HP range who need a durable, corrosion-resistant aluminum replacement with a 15-spline, right‑hand hub. It suits recreational anglers, family runabouts, and utility boat owners seeking predictable acceleration, straightforward installation, and reliable cruising behavior—provided the diameter, pitch, spline count, and rotation match the current setup.
