Quicksilver 877761Q01 oil filter is a high quality replacement designed for select Mercury and Mariner outboards, including 75-115hp models and the Mercury 150hp EFI 4-stroke.

This filter is built to Mercury Marine OEM specifications, helping to support proper lubrication and compatibility with your engine’s design.
Key benefits you may notice

In real world use, these design choices are intended to support clean oil flow, smooth startups after periods of storage or idle time, and simplified maintenance on the dock or in the shop. While results can vary by condition and use, the filter is designed to align with the needs of marine engines operating in salt air, sun exposure, and long boating days.
Real world use scenarios
On a busy weekend at the marina, quick service can mean spending less time under the hood. The filter’s compatibility with common service tools helps you replace it with minimal downtime. The robust metal shell resists corrosion in challenging saltwater environments, while the anti drain back valve contributes to prompt lubrication when you restart after a voyage.
