Tohatsu 90 HP outboard motor MFS90A ETL

Tohatsu MFS90A ETL 4-stroke outboard engine

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

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

Sea trial: with the Reitdieper 730, you can reach a maximum speed of 50 kilometers per hour with 3 people and the 90 hp outboard motor.

The synergy between the 4-2-1 Performance Tuned Exhaust and our precisely tuned ECU programming, MFS90 ensures strong acceleration when needed to get the boat planing faster and reach top speed sooner.

Equipped with standard features such as Variable Idle System allowing you to change idle speed from 650 to 850 RPM, a low gear ratio (2.08:1) giving you the higher low-end torque your boat needs, a freshwater flushing system designed to simplify routine flushing, and a powerful 41 amp alternator, the MFS90 offers the industry-leading features you expect from Tohatsu.

The design of the MFS90 is based on the best-selling models, the MFS40/50/60 and the MFS9.9/15/20. The legacy of the highest performing and most reliable engines has been passed on with a dynamic design and refined details to our all-new MFS90 4-stroke outboard with the industry's first innovative features and characteristics.

FEATURES

4-2-1 Performance Tuned exhaust
Isometric aggregated exhaust manifold "4-2-1 Performance Tuned Exhaust" maximizes torque and acceleration performance. This unique design is an industry first and is only found on Tohatsu outboards. By designing each exhaust passage to be of equal length, the merging 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 torque
From the 4-2-1 Performance Tuned exhaust, the MFS75/90/100/115 has the highest torque, allowing you to plane faster and reach top speed faster than all other competitors.

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

Superior durability and optimized weight
For high durability and weight reduction, Tohatsu has optimized every relatively heavy component, such as cylinder head, exhaust manifold, engine base, oil pan, lower unit, etc. Also, a special anodized process has been used on all major aluminum components for a longer engine life.

Excellent fuel efficiency
MFS75/90/100/115 has 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 operation and fuel efficiency.

Quiet engine
With the equal length intake manifold, the 4-2-1 Performance Tuned exhaust, and the precisely tuned ECU, the MFS75/90/100/115 delivers an exciting and performance-oriented engine sound. Also within the large capacity Idle Port, sounds reflect off each other to dampen the exhaust flow, contributing to the lowest idle noise.

Maneuverability
With its refined ECU programming, the MFS75/90/100/115 is designed to improve acceleration when needed to get the boat planing faster. When you open the throttle too wide, the ECU recognizes this and simultaneously ignites all four cylinders. At the same time, the ECU optimizes and delivers sufficient air and fuel, making the air/fuel mixture more suitable for rapid acceleration to generate higher torque. The higher the torque, the stronger the acceleration you get, resulting in improved hole-shots and thus faster planing. (Click here) Also, the upper and lower mounts and the gearbox are optimized for direct steering response and maneuverability and greater stability.

WHY TOHATSU

• Tohatsu from Japan has been around for over 100 years and produces more than 200,000 outboard motors per year. TOHATSU is the largest outboard motor manufacturer in the world.
  
  
• Tohatsu has more than 10 percent market share in the Netherlands and is growing fastest in market share in the Netherlands. For models up to 30 hp already more than 20% market share!
  
  
• Did you know that Mercury even has outboard motors up to 30 hp manufactured by Tohatsu? The only difference is the cowl and the price.
  The Tohatsu BFT models from 150 hp onwards have been re-branded Hondas since 2014. So you get a reliable Honda engine at a Tohatsu price.
  

• Tohatsu engines have the highest quality and a lower price than other A-brands. Tohatsu is also the only brand that exclusively produces outboard motors, so it has truly specialized.
  
  
• Tohatsu pays great attention to the appearance of its outboard motors, and this is reflected in this model. The appearance is tough and robust. Under the beautifully streamlined cowl you will find the trusted Tohatsu technology, developed for years of boating pleasure with minimal maintenance.
  
  
• The Tohatsu engine is user-friendly in every respect. For example, the oil filter is positioned so that you can easily replace it yourself. The lubrication of your outboard motor is optimal thanks to the generous oil reservoir. By applying the proven Tohatsu electronic injection system, your engine starts quickly and the throttle response is fast. The RPM can be smoothly controlled.
  
  
• Your newly purchased Tohatsu outboard motor comes with no less than 5 years full factory warranty.
  

• Tohatsu always performs well in comparative tests.
  • Read the test reports for, among others, the 15 and 30 and 60 hp engine. Tohatsu is the price-performance winner according to Boote Testen.
  • ANWB 'Waterkampioen' also conducted an Outboard Engine Test. The Tohatsu 6 hp emerged as the winner based on factors such as weight, noise, and ease of use. According to ANWB, it is best to buy a Tohatsu 6 hp outboard engine.
  • Boote-Magazin.de also tested the Tohatsu MFS115 A : impressive result due to the best torque-to-weight ratio and higher top speed. Due to its small displacement, the Tohatsu is also extremely fuel-efficient.
• Most models are available from stock!

  Available propeller sizes:

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

If the RPM at full throttle is too low, a smaller pitch can provide higher top speed and acceleration. A difference of 1 pitch size results in an approximate difference of 200 to 300 RPM. Note: choosing too low a pitch can lead to exceeding the maximum RPM and thus to engine damage.

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