Tohatsu 90 HP outboard motor MFS90A ETL

Tohatsu MFS90A ETL 4-stroke outboard motor

The groundbreaking technology, the 4-2-1 Performance Tuned Exhaust, delivers unparalleled torque across the entire RPM range. The higher the torque, the better the hole shot, which translates to higher speeds. Higher torque also means less drag, which in turn means more boating options; it can be used on any type of boat, from light to heavy, pleasure craft to commercial.

A rule of thumb is that for fast boats, you need 1 hp for a total weight of 10 to 20 kilograms. Based on this, this outboard motor is suitable for a total weight of 1 tonne to 2 tonnes.
For displacement boats, 1 hp per 150 to 200 kilograms is sufficient; then the engine is adequate for 13 to 18 tons of total weight.

Sailing test : with the Reitdieper 730 can be reached with 3 people using the 90 hp outboard motor, up to a maximum speed of 50 kilometers per hour.

The synergy between the 4-2-1 Performance Tuned Exhaust and our precisely tuned ECU programming, MFS90 delivers strong acceleration when needed to get the boat on plane quicker and help you reach top speed faster.

Equipped with standard features like the Variable Idle System that allows you to change the idle speed from 650 to 850 RPM, a low gear ratio (2.08:1) that gives you the higher low-end torque your boat demands, a freshwater flush system designed to simplify routine flushing, and a powerful 41-amp alternator, the MFS90 delivers the industry-leading features you expect from Tohatsu.

The MFS90's design is based on our best-selling models, the MFS40/50/60 and MFS9.9/15/20. This heritage of high-performance and reliable engines has been carried over to our all-new MFS90 4-stroke outboard engine, featuring industry-first innovative features and design elements, with a dynamic design and refined details.

FEATURES

4-2-1 Performance Tuned exhaust
The isometric aggregate exhaust manifold "4-2-1 Performance Tuned Exhaust" maximizes torque and acceleration. This unique design is an industry first and is only found on Tohatsu outboards. By designing each exhaust passage to be the same length, the combination of the exhaust from each cylinder creates additional suction that helps pull the exhaust out of the engine. This completely eliminates the possibility of exhaust interference and dramatically improves performance.
Video with details is on this page.

Excellent couple
From the 4-2-1 Performance Tuned exhaust, the MFS75/90/100/115 has the highest torque allowing you to get on plane quicker and reach top speed faster than any other competitor.

**Data based on research conducted and collected by Tohatsu Engineering Department

Superior durability and optimized weight
To ensure high durability and weight reduction, Tohatsu optimized each relatively heavy component, such as the cylinder head, exhaust manifold, engine base, oil pan, lower unit, etc. A special anodizing process was also used on all major aluminum components for extended engine life.

Excellent fuel efficiency
The MFS75/90/100/115 features a unique SOHC-4V design in its class, where competitors are either SOHC-2V or DOHC-4V. Spark plugs are strategically placed in the center of each combustion chamber for the most efficient combustion with optimal heat conduction, resulting in strong running and fuel efficiency.

Silent engine
Featuring a equal-length intake manifold, 4-2-1 Performance Tuned exhaust, and a precisely tuned ECU, the MFS75/90/100/115 delivers an exciting, performance-focused engine note. Sounds also bounce off each other within the large-capacity idle port, dampening the exhaust flow, contributing to the quietest idle noise.

Agility
With its sophisticated ECU programming, the MFS75/90/100/115 is designed to improve acceleration when needed to get the boat on plane quicker. If you open the throttle too wide, the ECU recognizes this and fires all four cylinders simultaneously. At the same time, the ECU optimizes and delivers sufficient air and fuel, making the air/fuel mixture more suitable for quick acceleration to generate higher torque. The higher the torque, the stronger the acceleration you get, resulting in improved hole shots and therefore faster planing.

  Available propeller sizes:

Choose a lower pitch for heavier boats: higher acceleration (for waterskiing/wakeboarding). Higher pitch for lighter boats: higher speed.

If the RPM is too low at full throttle, a smaller pitch can result in a higher top speed and acceleration. One pitch makes a difference of about 200 to 300 RPM. NB: Choosing too low a pitch may result in exceeding the maximum RPM and thus in engine damage.

You can also achieve more pulling power and higher revs with a larger diameter, and less pulling power and higher revs with a smaller diameter.
