FEATURES

Steering Options

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.

Multi-function tiller handle with height adjustment

The multi-function tiller handle is equipped with 3-position height adjustment with optional accessory to provide an additional 4-position height adjustment.

17.5 amp high-output charging system

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.

Optimum engine mount locations

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.

Minimal water drag gear case

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.

Newly designed flywheel

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.

Whole new intake manifold

The intake manifold has been completely redesigned with resin to reduce weight by 48%.

Additional auxiliary water intake port

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.

No-mess oil filter drip pan

The newly adopted oil filter drip pan provides improved serviceability, reduces waste and keeping an environmentally conscious mindset.
