We carry trusted marine filtration brands such as Sierra, Mercury, Yamaha, Volvo Penta, and Wix, offering exact-fit replacements for both outboard and inboard engines.
Why Marine Oil Filters Matter
- Protect Engine Components: Filters out debris, metal shavings, and sludge to prevent internal damage.
- Maintain Oil Quality: Keeps oil clean longer, reducing the need for frequent changes.
- Withstand Marine Conditions: Built to resist corrosion from saltwater and humidity.
- Reliable Oil Flow: Anti-drainback valves and bypass systems maintain consistent lubrication under pressure.
Types of Marine Oil Filters
| Filter Type | Key Features | Best For |
|---|---|---|
| Spin-On Filters | Easy installation and removal, built-in valves | Outboard and sterndrive engines |
| Cartridge Filters | Replaceable element, eco-friendly housing | Inboard and diesel applications |
| High-Capacity Filters | Extended service life and enhanced dirt-holding capacity | Heavy-duty or commercial marine engines |
How to Choose the Right Marine Oil Filter
- Engine Compatibility: Always match filter specifications to your engine’s make and model.
- Micron Rating: Choose filters that capture fine particles (typically 10–25 microns).
- Material Quality: Select filters with corrosion-resistant steel and marine-rated gaskets.
- Service Interval: Replace filters every 100 engine hours or at least once per season.
Pro Tip
When replacing your marine oil filter, always inspect and clean the sealing surface, lubricate the gasket, and hand-tighten the new filter for a secure seal. Never reuse an old gasket — it can cause oil leaks and pressure loss.

Frequently Asked Questions
Q: How often should I replace my marine oil filter?
A: Replace your oil filter every 100 hours of engine use or once per boating season — whichever comes first.
Q: Are marine oil filters different from automotive filters?
A: Yes. Marine filters are designed to handle salt, moisture, and vibration, providing stronger seals and corrosion protection.
Q: What happens if I don’t change my oil filter regularly?
A: Dirty filters restrict oil flow, reduce lubrication, and can cause overheating or engine failure.
