Built from high-strength polished aircraft-grade aluminum, it emphasizes durability and resistance to steering system binding. Choose this when you operate bigger outboards and need substantial engine height and setback adjustments for performance gains.
Who it’s for: anglers and boaters with higher HP motors who require substantial engine repositioning. Limitation: heavier and may require more transom support and mounting space.
Buying Guide
What should I consider when choosing a jack plate?
- Engine horsepower and weight: Ensure the jack plate supports the motor’s HP and weight. Higher HP often benefits from larger height and stronger mounts.
- Setback and height range: More setback increases engine trim leverage, affecting planing and handling. Align setback with boat type and typical load.
- Material and build quality: Aluminum plates resist corrosion, but some models include bronze or brass hardware to reduce binding. Consider marine-grade materials for longevity.
- Adjustability type: Manual vs. powered (pump or electric). On-water adjustability is convenient but may add complexity and cost.
- Installation and compatibility: Check mounting holes, transom thickness, and mounting hardware included. Wooden blocks or mounting pads may be included for proper alignment.
