O’Sullivan’s Marine aim to deliver the ultimate boating experience by providing outboard motors that are simple, easy to use and of outstanding quality. Tohatsu, one of our most popular brands, have just launched a new range of engines that we are particularly excited about!



THE ALL NEW TOHATSU 4 STROKE MFS75/90/100/115HP


With this new range of engines, Tohatsu have certainly delivered responsive acceleration, fast top end speed and simple engine operation that offers you a fun and memorable boating experience!

Revolutionary Design
Horsepower is determined by displacement and maximum RPM, but increasing displacement makes the weight increase, which is not a favourable option. Minimising displacement, yet at the same time maximising the performance of acceleration was the biggest challenge in designing these new engines. To address this Tohatsu have re-imagined the conventional stereotype exhaust system to create a ‘4-2-1 Performance Tuned Exhaust’ giving maximum torque and acceleration performance: The length of exhaust passage for each cylinder is equal in length to promote best performance throughout the entire RPM range - The exhaust gas from cylinders #1 and #4 combine to one, and cylinders #2 and #3 combine as one. - Those two passages merge to create the best exhaust flow by creating extra suction to help pull the exhaust from the engine. - This design eliminates the interference of exhaust gas compared to a regula 4 to 1 exhaust manifold. - This is the first outboard motor to embrace this industry leading design.

Easier Maintenance
Maintenance features are key to engine longevity. Tohatsu have added new features for easier maintenance:

An oil catch tray for cleaner oil filter changes.
An auto-tensioner for stress free timing belt adjustment.
Roller locker arms for minimal friction for reduced wear.

Summary of Characteristics
*Unique 4-2-1 Performance Tuned Exhaust manifold has been designed to maximize
low end torque and acceleration performance.
* Best in class torque – displacement ratio creates excellent performance for all styles
of boats from light weight to heavy weight.
* Key elements of Simpliq ™ Technology; Simple Architecture, Easy to Use Interface
and Absolute Quality are all in these models

Tohatsu have also added the very stylish ‘BELUGA WHITE’ model for their existing MFS50 and 60HP long shaft engines, as well as the new MFS115HP Long and Ultra Long shaft.
