Continuing the legacy.

Offers increased durability and easy maintenance for commercial use.

Standard Features
  • Phantom Black
  • Command Thrust Gearcase.
    The 60 and 40hp SeaPro FourStroke engines come standard with the Command Thrust gearcase. Its larger torpedo, combined with a bigger-diameter prop, can lift a heavy boat onto plane more easily and hold it there at lower speeds without impacting top speed.
  • Corrosion Resistance.
    Mercury's proprietary formula - XK360, is an extremely low copper content aluminium alloy, which leads the industry in corrosion resistance. This makes costly corrosion failures and high labour bills a thing of the past. Most competitors use alloys with 2% to 4% copper content which will corrode faster than our MercAlloy, XK360 or A356 alloys
  • Easy maintenance.
    A pictorial maintenance decal and owner's manual supplement for the 60 and 40hp SeaPro FourStroke engines make simple service and maintenance even easier by providing step-by-step instructions.
  • Easy to Gauge.
    Accurate digital information is presented in a clean, easy-to-read gauge for instant, reliable information at a glance. Combined with additional sensors, Mercury's standard gauges are powerful tools to provide safety and comfort while on the water.
  • Engineered for Commercial.
    Engineered to deliver longer engine life while maintaining the power and performance necessary to get the job done, the 60 and 40hp SeaPro FourStroke engines are validated to three times the engine life of a recreational engine.
  • Heavy-Duty Improvements.
    Engine improvements on the 60 and 40hp SeaPro FourStroke engines will deliver extended life and reliability in harsh, high-hour commercial applications.
  • Repower with SeaPro.
    The compact size also means older boats that were not initially designed for the weight of heavier four-strokes can now be repowered and reborn to perform at their best with the latest technology.
