Performance & Practical Benefits

A 100-hour service is one of the most meaningful steps you can take toward preserving engine performance. With this Mercury Marine part number 8M0147049, you’ll feel the difference immediately — smoother idling, steadier acceleration, and more consistent temperature and oil pressure readings. Clean filtration keeps buildup from robbing your power, while the fresh gearcase seals help maintain a tight, dry, and well-protected lower unit.

The components install easily, thanks to precise OEM fitment. Everything threads on securely and seats with that reassuring “just right” tension you only get from genuine Mercury parts. No rattles. No leaks. No worries about compatibility. Just a reliable, predictable service that gets you back on the water faster and with more confidence.

And because everything arrives in one box, you avoid the usual runaround of mismatched parts or last-minute store trips. It’s smart, efficient boating — the kind every seasoned owner appreciates.

Why Buy OEM

When it comes to engine maintenance, cutting corners never pays off. OEM parts give you the quality, precision, and longevity your MerCruiser engine was designed for. Mercury’s filters and seals are engineered to hold up in real marine conditions, from long idle hours in the marina to the hot, high-load demands of open-water cruising.

Choosing Mercury means fewer surprises, better long-term protection, and components that work seamlessly together. It’s the choice you’d recommend to any fellow boater who cares about doing things the right way the first time.
