Two-piece high-strength aluminum alloy plate mounted on the lower unit of Navy outboard motors to help improve performance by preventing surface air from being sucked in by the negative pressure side of the propeller blades.
We recommend that you mount the plate about 20% of the propeller diameter (about 5-6 cm) above the propeller.
This model fits Navy 3.0 Evo and older (non-Evo) Navy 6.0 Evo models.
