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 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.
The Power You Need.
25hp SeaPro two-stroke motors come with capacitor discharge electrics for increased charging output, more durability and reliability.
