Multi-port Programmed Fuel Injection adds both easy starts and improved fuel efficiency - without sacrificing performance. It delivers precise amounts of fuel and air to each cylinder, for easy starting, instant throttle response, and excellent fuel efficiency.

Tough Corrosion Resistance

Corrosion Resistance

Critical interior components use a high corrosion resistant aluminum alloy, resulting in a more durable engine and gear case.

Extra Anodes

Extra anodes provide longer life.

HI-M Coating

Bolts and brackets are treated with a special HI-M coating for superior surface finishing and corrosion resistance.

4-Front Corrosion Protection System

Honda’s exclusive 4-Front Corrosion Protection System offers a patented, double-sealed multi-layered paint process.

Fresh Water Flushport

A fresh water flushport flushes debris and saltwater out of the engine.

Legendary Reliability

Unmatched peace of mind

Honda's True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the last day as it is on the first.

Honda Quality

Our outboards share many technologies and components used in Honda vehicles, with all the benefits of years of proven Honda engineering, precision manufacturing and reliability.

Extreme Duty Gearcase

Honda's high performance gear case is designed specifically to withstand the extreme duty cycles of law enforcement and military patrol boats for maximum performance and durability.

Engine Alert System

The Engine Alert System monitors vital engine functions and prevents engine damage by alerting the operator of: overheating, water in fuel, low oil PSI, battery, over-rev, and critical engine function.

2-Pass Cooling System

The unique cooling system passes through each aluminum exhaust manifold, the cylinder heads, and once again through the exhaust manifolds. This results in increased cooling efficiency and long-term durability.

Simple, Effortless Control

iST: Superb Control

Honda's exclusive Intelligent Shift and Throttle (iST) command and control system delivers superb control plus plug-and-play installation of Honda Marine products and third-party controls and devices.

Easy Ownership

Simplified maintenance

The little things make a big difference. The M300 is designed to reduce maintenance time for routine tasks like oil and filter changes.

3 latch lock & seal cover

Easy to remove and carry the cover, simplifying maintenance access.

On-board connectivity

NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as SONAR or GPS.

High Output Charging for more usable power

The charging system features a 90 amp "On Demand" belt-driven alternator with 60 charging amps. This superior design reduces heat buildup and provides outstanding battery charging across the RPM range.
