1.8L DOHC four-stroke, 4-cylinder engine
The Yamaha 115hp Jet Outboard Engine redefines what boaters can achieve in shallow rivers, rocky-bottom lakes, and treacherous shoals. Unlike traditional propeller-driven outboards, Yamaha’s Jet Drive system allows you to navigate waters that would normally limit or damage conventional engines. By removing the propeller and gearcase, this engine enables ultimate maneuverability, reliability, and fuel efficiency, giving adventurers the freedom to explore previously inaccessible waterways.
Whether you’re running a deck boat through rocky rivers or navigating a deep-V hull across shallow estuaries, the Yamaha 115hp Jet Outboard Engine delivers consistent performance with Yamaha’s renowned engineering standards.
Yamaha’s Jet Drive outboards are engineered to handle extreme shallow-water conditions:
Prop-Free Design: Avoids damage from rocks, stumps, and submerged debris.
Enhanced Maneuverability: Move around obstacles easily, including sandbars and shoals.
White-Water Capabilities: Safely traverse rapids without risking a bent propeller.
The Yamaha 115hp Jet Engine combines lightweight efficiency with robust power:
1.8L DOHC four-stroke, 4-cylinder engine
16-valve setup with 4 valves per cylinder
Produces 80hp in Jet Drive configuration
Long tube intake tracks for optimized water flow
Yamaha builds engines to last with corrosion-resistant technology:
Phaze Five™ Anti-Corrosive Paint System: Five-layer protection against harsh water conditions
YDC-30 Alloy: Proprietary alloy ensures durability and resistance to wear
2-Year Warranty: Confidence in Yamaha’s reliability
The engine also prioritizes user convenience:
Power Trim & Tilt: Adjust engine angle for optimal performance
Freshwater Flush Device: Easy engine flushing without running it
Lightweight Design: At just 377 lbs, the engine is easy to mount and transport
Unmatched shallow-water capabilities
Excellent fuel efficiency
High durability and corrosion resistance
Smooth, powerful acceleration
Remote mechanical steering for precision
Slightly lower horsepower compared to prop-driven 115hp outboards
Jet drive can generate more cavitation at high speeds in certain hulls
Maintenance requires awareness of jet pump and impeller system
Pre-Launch Check: Inspect the jet intake for debris before launching.
Engine Flushing: Use the freshwater flush device after every saltwater trip.
Trim Adjustment: Adjust power trim for shallow water vs. deeper runs.
Steering Practice: Jet drives handle differently than propellers—practice tight turns.
Fuel Management: Keep the EFI system clean for consistent performance.
Marine professionals frequently recommend the Yamaha 115hp Jet Outboard Engine for shallow-water exploration.
Guides in Alaska and Florida: Report that the jet system enables access to rivers and coastal flats previously off-limits.
Deck Boat Owners: Praise the engine’s acceleration and maneuverability when loaded with gear.
White-Water Enthusiasts: Note minimal risk of engine damage when navigating rapids.
According to industry reviews, the Yamaha Jet Drive outperforms prop-driven engines in extreme conditions, offering more versatility and fewer maintenance headaches.
