35+ years of unsurpassed quality and service
The MFS25D is designed for a wide variety of boat applications, such as inflatable, aluminum, and fiberglass. Available in a wide variety of options, MFS25D will meet whatever configuration you need for your boat.
We have achieved the lightest weight in its class and improved reliability, without sacrificing performance. Tohatsu strives to deliver a smarter and more exciting boating experience.
Unique to the MFS25/30D, we have redesigned the tiller handle to include a stop switch, a four-step trolling speed control system from 750 RPM to 1050 RPM, forward – neutral – reverse shifter, throttle friction adjustment, and electric start button on certain models. Tohatsu’s multi-function tiller handle is also available for multiple model options. Both standard and multi-function tiller handles have trolling speed control feature. Remote control models are also available.
The multi-function tiller handle is equipped with 3-position height adjustment with optional accessory to provide an additional 4-position height adjustment.
The electric start models include the best in class 17.5 amp high-output charging system. This is achieved by applying stronger magnets on the magneto and a water-cooled rectifier. These improvements produce the highest alternator output without increasing weight.
We have repositioned the engine mount locations and optimized the distance between the upper and lower engine mounts by bringing the upper mount and lower mount forward from the center of driveshaft. Our revamped design reduces vibration and increases maneuverability for a better boating experience.
Tohatsu’s newly designed gear case has been given a more torpedo-like shape for optimal hydrodynamic flow, reducing water drag and improving performance – from planing to top end speed. A gear ratio of 2.17:1 optimizes low end torque and the ability to turn a wider variety of propellers for many boating applications.
The newly designed flywheel creates airflow inside the cowling. This improves the internal air circulation and reduces the temperature of electrical components to maximize reliability.
The intake manifold has been completely redesigned with resin to reduce weight by 48%.
The MFS25/30D(W) gear case includes an additional auxiliary water intake port, providing consistent cooling water circulation. This allows the cooling water come up to cool the engine even if the primary water inlet were covered by marine debris.
The newly adopted oil filter drip pan provides improved serviceability, reduces waste and keeping an environmentally conscious mindset.
