Command Thrust Gearcase
The 60 and 40hp SeaPro 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.
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 labor 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.
Calculate your fuel savings
The Mercury Fuel Savings Calculator will allow you to easily calculate the possible fuel savings of a Mercury FourStroke SeaPro over a TwoStroke!
Choose how you use your boat, select the TwoStroke and FourStroke horsepower - and our tool will show your potential fuel savings. If you're looking to upgrade or add more power, you can even choose different FourStroke and TwoStroke horsepower options!
SmartCraft compatibility for 25hp and higher SeaPro outboards makes every job easier thanks to intelligent digital gauges, touchscreen VesselView® displays and advanced technologies such as Troll Control and Active Trim, which help you maintain engine speed and optimize performance.
