Mariner Marathon commercial outboards are designed to work as hard as you do. Engineered to be ultra-resilient working partners for everyone making their living on water, they've earned their credentials for reliability by performing under the toughest working conditions possible to deliver trouble-free operation year after year.
On selected models, big tiller comes as standard which delivers essential commercial benefits: the more room in the boat and easy hands-on control of the engine with integrated shift, trim and throttle controls.
Whatever your job, there's a specific Mariner Marathon model to suit it.
Marathon engines are specifically calibrated to achieve much longer engine life, ensuring reliability and performance when you need it most.
Most Four-Stroke engines have up to 30% better fuel efficiency than Two Strokes, allowing you to go further on less fuel.
Mariner's proprietary formula, XK360, is an extremely low-copper-content aluminium alloy, which leads the industry in corrosion resistance. Costly corrosion failures and high labour bills are a thing of the past.
Lightweight, durable materials and fewer moving parts than competitive Four Stroke engines have made the marathon tough, compact, durable and highly efficient.
