Tohatsu/Mercury 4, 5, 6 HP Outboard Motor Stabilizer - No Drilling Required

New Improved Model
For Tohatsu/Mercury 4, 5, 6 HP 2-stroke and 4-stroke models: MFS4, MFS5, MFS6

By modifying the bend shape and slightly increasing the dimensions, this stabilizer provides improved performance and increased top speed compared to previous models.
While increasing size usually increases resistance, the altered bend shape reduces it.
Furthermore, changes to the reinforcing bracket shape allow it to clear the water inlet and anode, providing greater installation flexibility.

Can be installed without modifying the outboard motor itself.

[Stabilizer Effects]
Planing is a state of navigation where lift, far greater than buoyancy, supports the object.
The lift acting on the hull raises the boat, and in a planing state, the bow lowers, characterized by gliding over the water at a trim angle (longitudinal tilt) of 3° to 5°.
Therefore, the stabilizer constantly generates lift on its underside at a trim angle of 3° to 5°.
This lifts the outboard motor, allowing it to reach a planing state more quickly.
This product is designed with a unique bending process to ensure water flow and maintain planing effectiveness.
Please experience the effects of this stabilizer for yourself.

Material: SUS304 (Stainless Steel), 2B finish, 2.0mm thickness
Laser cut and bent

Highly resistant to saltwater corrosion (rust) and exceptionally strong due to the bending process.

Modifying the outboard motor (drilling holes) can peel the paint and cause corrosion, but this product can be installed without modification, eliminating concerns about corrosion.
Install by sandwiching the cavitation plate.
Reinforcing plates are included to be attached as one or two pieces to the area without protrusions on the underside of the cavitation plate.
Modifications may be required depending on the model year.
Left and right plates, reinforcing plate for the underside, and mounting bolts (stainless steel) are included.

This is an original product.

Note: May have scratches, oil stains, burn marks, dross, burrs, etc. from the manufacturing process.

Please judge from the images.
