4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
Increased Displacement For More Power
Displacement on the 25HP and 30HP have been increased to 552 cc (33.7 cubic inches), providing 4% more torque in midrange operation.
Center Mount Tiller
Ergonomically designed tiller handle is longer for improved handling. Adjustments for throttle and steering friction allow easier control. Up front shift lever, PTT switch, and engine alert lamps provide added convenience

3 to 3 Induction
A compact 3-cylinder, 3-carburetor design utilizes one carburetor per cylinder. More responsive than competitive throttle bodies with long intake runners, the design provides smooth, quiet operation, along with instant throttle response and performance.

PGM Ignition
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.
Auto Start Enrichment (ASE)
Just like a fuel injection system, Auto Start Enrichment automatically adjusts the air-fuel mixture for quick, easy starting and warm-up.
Non-Linear Mounting System
Patented non-linear rubber mounts provide smoother operation at all engine speeds.
Positive Lubrication
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
Engine Alert System
Audio and visual cues combine with RPM reduction circuits to alert the operator of overheating, low oil PSI and over-revving to prevent engine damage.
Forced Air Ventilation
Unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. The ventilation system reduces under-the-hood operating temperature, improving performance and long-term durability of the electrical components.
3 Inlet Cooling
Provides plenty of water to maintain optimum engine temperature in all conditions.
Regulated Charging System
A rectifier/regulator is standard on both manual and electric-start models. On manual models, you have the convenience of 4 Amps to charge the battery, and on electric-start models, a high-output 10 Amp system.
Corrosion Protection System
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
Fresh Water Flushport
Flushes debris and saltwater out of the engine, extending the life of the outboard.
Easy Maintenance
Front-mounted oil filter and oil fillers simplify maintenance, while "screw-type" valve adjusters reduce maintenance costs.
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
Gas Assist Tilt
A gas-filled cylinder makes it easy to tilt the engine for running in shallow water, or to raise it completely out of the water for protection.
Forward Mounted Shift Lever
Provides easy access to the forward-mounted controls.
Power Trim/Tilt
Allows user to trim the unit for maximum performance and handling.
Trim Range: - 4° to +12°
Tilt Range: 67°
Ultra Low 3 Star Carb Emissions
Environmentally friendly technology.
