Yamaha 13x19 Aluminum Propeller for 50-130 HP (OEM 6E5-45941-00-EL)

This Yamaha 13x19 aluminum propeller is a genuine OEM part (part number 6E5-45941-00-EL) made for mid-range Yamaha outboard engines roughly in the 50 to 130 HP range. It belongs to Yamaha’s K-series propellers – a standard aluminum prop line widely used across many models, known for reliable performance and fit. It’s compatible with a broad selection of Yamaha outboards, including both two-stroke and four-stroke models (for example, the F50-F60, F75-F90, F100-F115, and some older 115-130 HP engines), making it a versatile choice for a variety of boats.

With a 13-inch diameter and 19-inch pitch, this 3-blade propeller is engineered to provide excellent top-end speed without completely sacrificing acceleration. The steep 19″ pitch allows a suitably powered boat to achieve higher speeds, as the prop moves a large amount of water with each rotation. This makes it ideal for faster boats, RIBs, and runabouts that have enough horsepower to turn the prop up to the proper RPM range. While the 19″ pitch is geared toward speed, the large 13″ diameter and three well-designed blades ensure the prop still generates solid thrust at lower speeds. At mid-range RPM, your boat will maintain a fuel-efficient, smooth cruise, and at wide-open throttle, it can reach an impressive top speed.

As a genuine Yamaha product, this propeller is built from high-quality aluminum and includes a molded-in rubber hub. The hub absorbs vibrations and helps protect the engine’s gearing from shock when shifting gears. The factory finish (Yamaha’s aluminum props are typically painted white) is highly resistant to corrosion, specifically formulated to endure the rigors of saltwater operation. Installing the prop is straightforward – the 15-spline hub fits directly onto the output shaft of Yamaha outboards in this class with no modifications. You’ll use the same thrust washer, prop nut, and cotter pin setup as with the original prop. By equipping your engine with this 13x19 propeller, you’ll ensure optimal performance – strong acceleration on a light boat and a high top-speed potential – all with the peace of mind that comes from using an OEM Yamaha part designed for your engine.

Recommended Uses and Applications:

• Best suited for medium-sized boats (~15 – 20 ft), such as bowriders or RIBs, powered by Yamaha outboards around 70-115 HP – provides high cruising speeds and the potential for excellent top-end performance
• Great choice if you want to lower engine RPM at a given cruising speed – the 19" pitch enables the engine to run more economically at higher boat speeds (lower revs for the same speed)
• Recommended when replacing a lower-pitch prop that caused the engine to over-rev – switching to this 13x19 will properly load the engine and keep it within its optimal RPM range at WOT
• Serves as a reliable spare or replacement for the stock prop – with OEM quality and a corrosion-resistant coating, it ensures long life and safe operation in both freshwater and marine environments
