## Technical Specifications

### Key Features

• Electro-Polished Advantage: Unlike the standard finish (50480-001), this blade undergoes an electrochemical process that removes surface impurities. This results in a mirror-like shine that is significantly more resistant to pitting, oxidation, and marine growth in harsh saltwater environments.

• Thicker Steel Construction: To compensate for the smaller surface area, Lenco uses 11-gauge stainless steel. This provides extra rigidity, ensuring the blade does not warp or flex under the high hydraulic pressure typical of high-speed performance boats.

• Maximum Clearance: With only a 4-inch reach from the transom, this blade is the "problem solver" for technical poling skiffs, airboats, or dual-outboard setups where standard 9" or 12" deep tabs would hit the engine or swim platform.

• Direct Replacement: This is a 100% compatible "drop-in" replacement for any boat currently utilizing Lenco's limited-space series hardware.

### Installation Notes

• Component Only: Please note that part number 50480-021 includes the blade only. It does not include the 12V actuator, mounting brackets, or the switch kit.

• Symmetry: Trim tabs work in pairs; if you are upgrading from standard finish to electro-polished, it is recommended to replace both the port and starboard blades simultaneously to ensure uniform performance and appearance.

• Zinc Anodes: For maximum longevity in saltwater, consider adding a small sacrificial zinc anode to the blade to further protect the 304 stainless steel from galvanic corrosion.
