The Panther 4-Stroke Motor Bracket lets you adjust your trolling or auxiliary motor to five vertical running positions for changing water or load conditions. The anodized aluminum bracket is built to handle the increased weight and torque of today's four strokes with long or short shafts. Stainless steel torsion springs counterbalance the motor's weight, making adjustments a breeze. The 2" thick, extra-wide mounting board, along with aircraft-grade stainless steel hardware deliver heavy-duty performance. When installing, it is recommended that a backing plate is used, along with stainless steel mounting hardware (not included). Always use the safety cable that is included.
