The T-H Marine Z-Lock 8" Set Back Manual Jack Plate (JPZ-8-DP) is designed for boaters who want maximum setback and precise engine height control without the added cost or complexity of hydraulic systems. Ideal for performance-focused and shallow-water applications, this manual jack plate allows you to fine-tune engine height to improve hole shot, top-end speed, and overall handling.
