Mercury Marine 75hp-115hp 4 Stroke Outboard Oil & Filter Change Kit

Our review finds the Mercury Marine 75hp-115hp 4 Stroke Outboard Oil & Filter Change Kit is aimed at boat owners who perform routine maintenance on select Mercury FourStroke outboards and want a straightforward, correct-fit service solution. In this review the biggest reason to buy is convenience: the kit includes the exact OEM filter and Mercury Marine Engine Oil with the Flagship Protection formula, plus a hose and printed instructions, making an oil change simple and reliable when used on compatible 75hp, 90hp or 115hp EFI engines.

Key Features

• Genuine OEM part: The kit contains the original Mercury Marine P/N 8M0107510, ensuring correct fit and compatibility with specified engines.
• Complete service set: Each kit includes oil, filter, a hose and printed instructions so users have everything needed for a single oil change.
• Flagship Protection oil: The included Mercury Marine Engine Oil is formulated for improved camshaft wear protection and resistance to corrosion and oxidation.
• Engine-specific fit: Designed for most Mercury 75hp, 90hp and 115hp 4-Stroke EFI outboards with S/N 2B094996 and later, reducing fitment guesswork for those engines.
• Boxed instructions: Step-by-step guidance printed on the box helps users perform the service correctly without needing a separate manual.

Who It's For

The kit is best for owners of Mercury FourStroke outboards in the 75 to 115hp range who prefer OEM parts and want a quick, correct oil change without sourcing fluids and components separately. It suits DIYers comfortable performing routine maintenance and small shops who value an OEM packaged solution.

It is not the ideal choice for engines outside the stated serial range or for technicians who need bulk oil and filters for multiple services, since the kit is intended to cover a single oil change and some customers note the oil quantity may not satisfy every need.
