Honda Outboard Oil Filter 8–60 HP Engines (Part 15400-ZZ3-003) – Clean Oil for Small Motors

This Honda 15400-ZZ3-003 Oil Filter is tailored to Honda’s portable and mid-size outboards, from the BF8 and BF10 up through BF20, BF30, BF40, BF50 and BF60 horsepower models. Even though these engines are smaller in size, they work hard, often at high RPM, so filtering the oil is just as critical as in larger motors. Honda’s OEM filter uses a high-grade paper element that captures dirt, metal particles, and combustion residues, keeping the engine oil clean. By doing so, it helps maintain optimal compression and performance because clean oil ensures hydraulic valve lifters (if equipped) operate correctly and reduces friction on moving parts. Installing this filter is straightforward due to its spin-on canister design. It seals tightly to prevent any oil leaks, giving you peace of mind during operation.

• Reliable Engine Compatibility: Specifically recommended for Honda BF8, BF9.9, BF10, BF15, BF20 (twin-cylinder engines), and BF25, BF30, BF40, BF50, BF60 (three-cylinder engines) – basically all Honda 4-stroke outboards from 8 HP up to 60 HP. Using the correct OEM filter means it fits in the tight engine compartments of these smaller motors and meets Honda’s flow specifications.
• Ideal Use Cases: These engines often power small inflatable boats, dinghies, sailboat auxiliaries, fishing skiffs, and compact RIBs roughly in the 2.5 to 5 meter range. This oil filter is ideal for owners who rely on their smaller outboards for trolling, leisure cruising, or as backup kicker motors. It ensures your engine remains reliable on weekend trips and fishing outings by keeping the oil system in top shape.
• Maintenance Advice: Regular maintenance is key for small outboards that might run at high throttle for extended periods. It’s advised to change the oil filter with every oil change. Honda generally suggests every 100 hours or at least once per year. For engines used in harsh conditions (like silty or dusty water, or frequent short runs where the engine might not fully warm up), consider more frequent oil and filter changes. This will help avoid any buildup that could impede oil flow in these smaller oil circuits.
• Trusted Honda OEM Quality: By choosing this genuine Honda filter, you are ensuring the same build quality and material standards that your engine was designed with. The filter’s robust casing can handle engine vibrations, and its internal bypass valve (if present) will operate correctly under cold start or clogged conditions, unlike many cheap aftermarket alternatives. Protect your investment in your Honda outboard by using OEM filters that preserve performance, fuel efficiency, and engine longevity.
