This listing includes a pack of 12 filters, making it a solid option for shops, fleets, or stocking up on routine maintenance items.. This filter is designed to trap water and fine debris before fuel ever reaches the engine. It filters fuel down to 10 microns and is rated at 90 gallons per hour, which provides plenty of flow for most Yamaha outboards without creating restriction. That's especially important with today's ethanol fuels, which tend to pull moisture into the system and loosen debris from tanks and fuel lines.. You'll find this filter used on many Yamaha two-stroke and four-stroke outboards. For engines 115 horsepower
