Suzuki DF115SS 115HP Sport Series

The Suzuki DF115SS is a high-compression Sport Series FourStroke 115HP outboard engineered for strong performance in the North American maritime sector. Boasting a 2.0L inline four-cylinder DOHC powerhead with a 10.6:1 ratio and weighing 412 lbs, this unit offers an power-to-weight ratio for rapid acceleration. This 25-inch shaft model is perfectly matched for high-transom performance bay boats requiring dependable outboard propulsion systems with offshore propeller reach and rugged mechanical integrity for coastal navigation and sustained offshore power.

Peak operational performance for the Suzuki 115HP occurs between 5000 and 6000 RPM, ensuring consistent thrust delivery during high-speed transits. The strong 2.59:1 gear ratio facilitates the mechanical translation of the torque curve into rapid hole-shot capability and efficient hull planing. This engine exemplifies Japanese engineering reliability for offshore salt-water use, maintaining high thermal efficiency while resisting the corrosive effects of harsh environments during professional high-performance maritime operations.

High-Compression Engine Tech

The Sport Series FourStroke 115HP engine technology utilizes a 10.6:1 compression ratio to maximize power output. This sophisticated architecture helps support strong acceleration across the RPM band, providing the mechanical integrity needed for tournament-level fishing and high-speed coastal transit in marine offshore environments during long operational shifts.

Advanced Fuel Induction

The Multi-Point Sequential EFI system monitors atmospheric conditions for the appropriate fuel induction ratio. This technology is designed to support instant starting and prevents engine bogging, completely eliminating carburetor-related maintenance while ensuring rapid acceleration and clean combustion for professional long-range trips in unpredictable coastal waters.

Deep Propeller Authority

This unit’s hole-shot performance is stabilized by a 25-inch shaft designed for versatile high-transom heights. Its hydrodynamic profile helps support consistent propeller grip in rolling ocean swells, providing the captain with boat control during complex harbor maneuvers and high-speed offshore coastal transits in North American waters.

High Charging Authority

Featuring a high-output 40 Amp alternator, this outboard provides consistent charging to keep critical onboard electronics functional. This electrical authority supports high-definition fishfinders and navigation displays, ensuring that your primary power source acts as a reliable battery maintainer during extended offshore fishing missions and tournament transits.

Suzuki 115HP Warranty

Every Suzuki 115HP is backed by a comprehensive 3-Year Limited Warranty for American boat owners. This factory-level protection covers structural and mechanical defects, ensuring access to genuine replacement parts and certified technicians, reflecting a deep commitment to long-term maritime reliability and professional technical support throughout the US.

Offshore Performance Match

This 115HP unit is specifically matched for high-transom performance hulls and offshore walkarounds. Its high-compression torque and extra-long shaft make it perfectly suited for coastal tournament fishing or as a dependable primary power source for large recreational vessels navigating rolling deep-water maritime environments safely.

Maintenance & Longevity

Routine oil changes for the 5.5-liter wet sump system are essential for preserving tight engine tolerances in saltwater. Freshwater flushing after every excursion prevents internal salt deposits and maintains the cooling system’s long-term health.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
