YAMAHA Outboard Stabilizer for 4hp, 5hp, 6hp, 8hp Engines

New Improved Model
For Yamaha 4, 5, 6, 8 HP F4A.B F5A F6C (4-stroke) 4A 5C 6C 8C (2-stroke)

By increasing the bending shape and slightly expanding the dimensions, this stabilizer is more effective and provides a greater top speed increase than previous models.
While increasing size usually increases resistance, the change in bending shape reduces it.
Furthermore, the shape of the reinforcing bracket has been changed to avoid the water inlet and anode, allowing for greater installation flexibility.

Can be installed without modification to the outboard motor.

[Stabilizer Effects]
Planing is a state of navigation where a much larger lift force than buoyancy acts on an object to support it.
The lift force acting on the hull lifts the boat, and when planing, the bow lowers, and the boat glides on the water with a trim angle (longitudinal tilt) of 3° to 5°.
Therefore, the stabilizer also generates lift on its underside at a trim angle of 3° to 5°.
This lifts the outboard motor and allows it to reach a planing state more quickly.
This product is designed with a unique bending process to ensure water flow and maintain planing effect.
Please experience the effects of this stabilizer for yourself.

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

Resistant to saltwater (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 installed one or two on the area without protrusions on the underside of the cavitation plate.
Modifications may be necessary depending on the model year.
Left and right plates, underside reinforcing plate, and mounting bolts are included (stainless steel).

This is our original product.

Note: Scratches, oil stains, burn marks, dross adhesion, burrs, etc., may be present from the manufacturing process.

Please judge from the images.
