Everything you need to properly service your Mercury Verado V10 at the 100-hour mark — with the correct oil quantities spec'd for both right-hand and left-hand rotation engines. The V10 takes more oil than the L6, so we've done the math for you. Left-hand rotation kits include 3 bottles of lower unit fluid to meet the updated February 2025 fill spec of 74.4 fl oz. Select your engine rotation from the dropdown.
