OEM Outboard Fuel Filters & Separators

Water in ethanol-blended fuel is the most common cause of hard starting, rough idle and stalling on fuel-injected outboards, and the filter is the cheapest part in the fuel system to keep fresh. This collection holds genuine OEM fuel filters, filter elements and water separators for the three brands we are authorized for.

To see one brand only, go to Suzuki fuel filters, Honda fuel filters or Yamaha fuel filters and water separators.

Frequently asked questions

How often should fuel filters be changed?

Suzuki's schedule is to inspect the fuel filter every 100 hours and replace the low-pressure filter every 400 hours or 2 years. For Honda and Yamaha, follow the owner's manual. A boat-mounted water-separating element should be replaced at least every 12 months.

What is the difference between the engine filter and a water separator?

The engine has its own filter or filters under the cowling. A water separator is a larger canister filter mounted in the boat between the tank and the engine, and it catches water and debris before they reach the motor. Most rigs with a built-in tank use both.

What are the signs of a clogged filter or water in the fuel?

Hard starting, a rough idle, hesitation or loss of power under load, and stalling. Many engines also have a water-in-fuel warning.

Which filter fits my engine?

It depends on the engine family and year. Look up your model in the Suzuki parts diagrams or Yamaha parts diagrams, or send us the model and serial number.

What else should I check while I am there?

Fuel hoses and primer bulbs harden and crack with age. Everything else is under fuel system parts.
