T-H Marine 6" Hole Shot Plate f/Z-Lock™ Jack Plate

The T-H Marine 6" Hole Shot Plate for Z-Lock Jack Plate is a performance enhancement system designed for marine jack plate installations. This innovative accessory attaches directly to the underside of Z-Lock jack plates, dramatically reducing water drag during boat acceleration to deliver measurable gains in hole shot performance—the critical first seconds when a vessel launches from rest.

The 6-inch hole shot plate achieves a documented 18–20 percent improvement in acceleration off the hole, translating to a 2–3 second gain in departure time during typical operating conditions. This performance increase comes from the plate's geometry, which displaces water flow away from the hull and motor assembly during the initial thrust phase when hydrodynamic forces are most critical. The 1.45-pound weight distribution is calculated to integrate seamlessly with existing Z-Lock systems without introducing trim imbalance or additional drag during cruising speed.

This accessory is engineered for operators running jack plate systems on performance vessels, tournament bass boats, and offshore fishing platforms where launch acceleration directly affects competitive success and operational efficiency. The 6-inch model (JPZHSP-6) fits standard Z-Lock jack plate footprints and is field-proven by users prioritizing acceleration metrics. Installation requires no modification to existing plate hardware and can be completed in minutes without removing the jack plate assembly.

T-H Marine Supplies specializes in propulsion and trim optimization systems for marine platforms, and the Hole Shot Plate lineup represents the practical application of hydrodynamic principles to measurable real-world performance. The product category addresses a specific technical gap: standard jack plates provide vertical trim adjustment but do not optimize the water flow geometry during the transient acceleration phase.

Compatible with Z-Lock jack plate systems, the 6" Hole Shot Plate integrates with marine propulsion setups running outboard motors in the 150–300 horsepower range and is suitable for both salt-water and fresh-water environments.
