Aftermarket Standard 10-Micron Water-Separating Fuel Filter Assembly (PN: 90798-1M740)

Product Overview

Protect high-horsepower outboard engines from contaminated fuel with this Standard 10-Micron Water-Separating Fuel Filter Assembly. Designed as a high-performance aftermarket direct replacement for Part Number 90798-1M740, this standard-capacity assembly is engineered for higher fuel-flow demands, larger engine displacements, and high-horsepower marine applications.

It traps ultra-fine debris, rust, and dirt while separating over 99% of free water from fuel before it reaches fuel injectors or carburetors. Constructed from heavy-duty, marine-grade non-corrosive resin (PPS), it resists saltwater degradation and rusting. The clear inspection bowl features a high-visibility red float ring that rises to indicate when accumulated water needs to be drained using the integrated drain valve.

Key Features & Benefits

• High-Flow 10-Micron Filtration: Traps microscopic particulates while maintaining optimal fuel flow for larger displacement outboards.

• Corrosion-Proof Composite Body: Built with resin/composite housing designed to endure harsh marine environments without rusting.

• Clear Bowl with Level Indicator: Transparent bowl and floating red level ring make water detection and routine draining effortless.

• Ethanol Fuel Compatible: Engineered to safely handle standard unleaded marine fuels, E10, and E20 ethanol blends.

• Standard Capacity (YGF-01 Frame): Offers double the flow capacity and larger filtration surface area compared to the small (90798-1M745) assemblies.

Engine Fitment & Compatibility

Suitable Outboard Engines:

• Recommended For: 4-Stroke Outboard Engines from 70 HP up to 350+ HP (Yamaha, Mercury, Mariner, Suzuki, Tohatsu, Honda, etc.).

• Maximum Flow Rate: Up to 200 Liters / Hour (approx. 53 GPH).

• Hose / Barb Size: Designed for standard 8mm – 10mm (5/16″ to 3/8″) fuel lines.

Important Note: Recommended for 4-stroke outboard engines. Not recommended for 2-stroke pre-mix engines, as water-separating filters can strip the pre-mixed two-stroke oil out of the gasoline.
