Yamaha 115hp Jet Outboard Engine – Power That Redefines Shallow Water Navigation
Looking to explore shallow waters, rocky rivers, or white-water rapids without the worry of damaging your propeller? The Yamaha 115HP Jet Outboard Engine is engineered for these exact challenges. This rugged and reliable engine lets you navigate areas where traditional propped motors simply can’t go. It’s built not only for exceptional performance but also for longevity and fuel efficiency.
Powered by Yamaha’s advanced 1.8-liter F115 four-stroke platform, the jet propulsion system delivers an impressive 80hp at the pump—plenty for deck boats, fishing rigs, and deep-V hulls that need to cruise confidently through shallow or obstacle-laden water bodies.

Why Choose the Yamaha 115HP Jet Outboard Engine?
When performance, versatility, and reliability matter most—especially in waters that are unpredictable and shallow—the Yamaha Jet Drive shines. Whether you’re a commercial boater, an angler navigating rock-strewn rivers, or an outdoor enthusiast heading into white-water territory, this engine empowers your adventure.
Maneuverability Without Limits
The jet drive means no lower gear case or propeller hanging below the boat’s hull. That enables you to pass over rocks, shoals, and other hazards without getting hung up or sustaining damage. For river runners or shallow bay explorers, that freedom is game-changing.
Rugged Reliability and Corrosion Protection
Yamaha’s Phaze Five™ anti-corrosion paint system and proprietary YDC-30 alloy deliver a durable, 5-layer protective barrier against saltwater and freshwater corrosion. Whether you’re navigating the Colorado River or the Baltic coast, this engine stands up to the elements.
Effortless Maintenance
A built-in freshwater flush device allows for easy engine cleaning without needing to start it. This extends engine life and simplifies end-of-day boat care—no tools, no hassle.

Yes, we offer flexible payment options for qualifying customers. Contact us to learn more about financing terms, deposit requirements, and eligibility.
3. What is the main difference between a jet drive and a propeller outboard engine?
A jet drive uses an impeller to draw in and expel water, allowing the boat to glide over shallow or debris-filled waters. It doesn’t have an exposed propeller, making it safer and more capable in tricky environments compared to traditional propped engines.
4. How often should I flush or maintain the Yamaha jet outboard engine?
It’s recommended to flush the engine with freshwater after every use—especially in saltwater environments. Yamaha’s built-in flush system makes this easy, and scheduled maintenance every 100 hours helps ensure peak performance.

Absolutely. The engine is built with corrosion-resistant materials, including Yamaha’s YDC-30 alloy and Phaze Five™ paint system, which protect it from the harsh effects of saltwater operation.
