Tohatsu MFS90AWETL 90HP 20in EFI White FourStroke Outboard Motor

Description

Marine grade aluminum alloy encases the Tohatsu MFS90AWETL Outboard Motor propulsion system. The 1,995 cc four-stroke four-cylinder powerhead generates 90 horsepower at 5,500 RPM. Finished in durable commercial white marine coating, this 20-inch shaft motor powers government patrol craft, charter vessels, and coastal passenger tenders. Electronic multi-port fuel injection guarantees smooth acceleration and fuel conservation.

Pure marine aluminum alloy blocks resist salt water pitting under harsh marine atmospheric exposure. High-strength forged crankshafts absorb continuous torsional shocks from high-pitch propellers. A rubber impeller raw water pump drives seawater through internal heat exchange passages. The dry engine weighs 392 lbs, oil capacity is 4.4 quarts, and standard transom bolt brackets support quick installation.

Key Features of Tohatsu MFS90AWETL

Charter fleet operators buy Tohatsu MFS90AWETL inboard engine units to power offshore passenger launches. The commercial white paint finish resists solar UV fading and salt water film buildup.

• Factory white polyurethane finish reflects solar radiation to keep engine cowlings cooler.
• 1,995 cc four-cylinder displacement generates strong low-end torque for quick hull planing.
• Tuned 4-2-1 exhaust passages optimize cylinder gas evacuation for improved fuel economy.
• High-capacity 21-amp charging system keeps ship batteries charged during night operations.
• Precision power tilt and trim allows remote adjustment of running trim angle.
• Low-idle trolling speed switch adjusts engine revs between 650 and 850 RPM.
• MFS90AWETL white finish matches gelcoat colors on modern commercial charter vessels.
• Integrated water separator filter stops water contamination from reaching electronic injectors.

Combustion Data Operating Heat

Multi-point fuel injection at 3.0 bar pressure keeps cylinder temperatures stabilized between 160°F and 180°F. The 2.0-liter four-stroke engine outputs 135 lb-ft torque at 4,000 RPM to sustain heavy cruising displacement loads. Cruise fuel burn remains steady at 4.2 GPH at mid-throttle. Continuous raw seawater cooling prevents internal thermal stress across multi-hour non-stop commercial charters.

Transom Alignment Mounting Details

Standard outboard transom drilling patterns secure the engine bracket across 20-inch reinforced boat transoms. The 20-inch drive leg positions the propeller in clean water flow behind the keel. Underwater prop hub exhaust expulsion meets ABYC marine noise requirements. The bracket accepts standard hydraulic steering rams within a standard 32-inch engine well width.

Throttle Behavior Maintenance Protocols

Electronic and mechanical remote controls yield exact throttle response across the complete RPM range. This outboard is not engineered for dry land running, direct mud flat scraping, or extreme offshore competition racing. Strict compliance with standard service routines ensures long operational life across commercial charter fleets.

• Inspect external white cowling latches and oil dipstick levels each shift.
• Change engine oil, replace lube filter, and check lower gear lube every 100 hours.
• Replace water pump rubber impeller and primary fuel filter elements every 12 months.

Warranty Statement Shipping Contents

A 3-Year commercial limited warranty provides protection against factory manufacturing defects. Shipped in a reinforced wooden crate, the package includes the white 90HP outboard motor, helm wire harness, basic analog gauge package, transom bolt hardware, and comprehensive technical service guide.
