Aftermarket 10-Micron Small Water-Separating Fuel Filter Assembly (PN: 90798-1M745)

Product Overview

Protect your outboard engine from contaminated fuel with this 10-Micron Water-Separating Fuel Filter Assembly. Designed as a high-performance aftermarket direct replacement for Part Number 90798-1M745, this compact fuel filter assembly is engineered to fit into tight bilge and transom spaces.

It efficiently traps dirt, rust, particles, and separates over 99% of free water from your fuel before it reaches your fuel injectors or carburetor. Constructed from a high-strength, non-corrosive composite resin (PPS) body, it will not rust or degrade in harsh saltwater environments. The clear visual inspection bowl features a high-visibility red float ring that rises to indicate when water needs to be drained.

Key Features & Benefits

• High Efficiency Filtration: 10-micron element stops ultra-fine particles and separates 99%+ of water.

• Corrosion-Proof Construction: Durable resin/composite housing designed for saltwater and freshwater marine environments.

• Clear Viewing Bowl & Drain: Visual inspection bowl with a buoyant red level ring makes water detection and routine servicing simple.

• Ethanol Fuel Safe: Compatible with standard marine fuels as well as E10 and E20 ethanol blends.

• Compact Footprint: Space-saving design specifically created for smaller boats, dinghies, and tight motor wells.

Engine Fitment & Compatibility

Suitable Outboard Engines:

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

• Maximum Flow Rate: Up to 100 Liters / Hour (approx. 26 GPH).

• Hose / Barb Size: Designed for standard 7mm / 8mm (5/16″) or 10mm (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.
