Quicksilver 4-Stroke Oil Change Kit for Mercury 75-115hp - Complete

Our review of the Quicksilver 4-Stroke Oil Change Kit finds it best suited for owners of Mercury 1.7L 75hp, 90hp and 115hp outboards who want a single-box solution for routine service. The bottom line: this kit delivers the exact quantity of Quicksilver 25W-40 oil and a genuine Quicksilver filter to complete an oil change quickly, and its Flagship Protection formula is the single biggest reason to buy for anyone prioritizing long-term camshaft and engine wear protection. It reads like a no-nonsense maintenance kit rather than a parts scramble.

Key Features

• Complete oil supply: The kit includes five 1L bottles of Quicksilver 25W-40 so users get the correct amount of oil for a full change without leftover guessing.
• Genuine filter: A Quicksilver premium oil filter is included to ensure filtration matches factory expectations for engine protection.
• Advanced formula: The Flagship Protection 25W-40 is engineered with anti-wear additives and corrosion inhibitors to reduce camshaft wear and long-term engine wear.
• Compatibility: Packaged specifically for Mercury 1.7L 75hp, 90hp and 115hp four-stroke outboards so fit and fluid choice are optimized for those models.
• NMMA compliance: The oil meets NMMA FC-W and is FC-W Catalyst Compatible, which supports marine engine emission and performance standards.

Who It's For

This kit is ideal for Mercury outboard owners who do their own maintenance and want a tidy, OEM-alike solution: recreational boaters who run 75hp to 115hp 1.7L four-stroke engines, small fleets that service multiple vessels, or marinas that perform routine maintenance. It removes the need to buy separate bottles and a lone filter.

It is less suitable for owners of Mercury engines outside the listed 1.7L 75/90/115hp fitment or for those who prefer alternative oil viscosities for different climates. Also, buyers who require multiple filter size options should verify fitment before purchase because customer feedback notes mixed experiences with filter fit.

Pros & Cons

Pros

• Includes the correct oil volume and a genuine Quicksilver filter so a full change can be completed from one box.
• Quicksilver 25W-40 uses an advanced additive package for improved camshaft and wear protection over time.
• NMMA FC-W certification and catalyst compatibility support marine performance and emissions standards.
• Good value and convenience compared with buying oil and filter separately.

Cons

• Several customers report mixed filter fit, so buyers should double-check compatibility with their specific engine serial or model details.
• The kit is tailored to 1.7L 75/90/115hp Mercury outboards and will not be a one-size-fits-all solution for other engines or viscosities.
