T-H Marine Z-Lock 12" Set Back Manual Single Adjust Jack Plate – JPZ-12-DP

The T-H Marine Z-Lock 12" Set Back Manual Jack Plate (JPZ-12-DP) is engineered for boaters who demand maximum setback, leverage, and performance without the complexity of hydraulic systems. Designed for larger outboards and performance-oriented boats, this manual jack plate allows precise engine height adjustment to improve hole shot, top-end speed, trim response, and shallow-water capability.

Featuring Z-Lock™ single-adjust technology, the plate securely locks the engine in position, preventing unwanted movement even under high loads and aggressive operation. The 12-inch setback provides increased leverage and improved hull balance, enhancing propeller efficiency and overall boat handling. Constructed from high-strength aluminum and finished in a polished aluminum coating, the Z-Lock jack plate offers excellent corrosion resistance and long-term durability in both freshwater and saltwater environments.

Proudly made in the USA, T-H Marine Z-Lock jack plates are trusted by tournament anglers and performance boaters for their rugged strength, reliability, and straightforward manual adjustment.

Key Performance Features

Interlocking Z-Lock Design: The unique Z-Lock side rails eliminate the side-to-side movement and vibration common in standard jack plates. This design provides the rock-solid stability of a permanent mount while still allowing for vertical adjustments.
Single-Bolt Adjustment: Unlike many manual plates that require loosening multiple bolts on both sides, this model features a single top-mounted adjustment bolt. This allows you to raise or lower your engine height evenly and quickly with a single wrench.
High-Strength Construction: It is machined from 1/2" aircraft-grade aluminum and rated for the heaviest modern outboards, supporting up to 300 HP V6 engines, including high-torque four-strokes.
Premium Aesthetic: The "DP" (Dolphin Polished) finish provides a mirror-like shine that resists corrosion in both fresh and saltwater environments while adding a custom look to your transom.

Why Choose the Z-Lock 12" Manual Jack Plate

The T-H Marine Z-Lock JPZ-12-DP is ideal for boaters seeking maximum performance gains with a simple, manual solution. Its extended setback, secure locking system, and durable polished aluminum construction make it a dependable upgrade for high-performance outboard applications.

Summary for the User

The JPZ-12-DP is an ideal "set-it-and-forget-it" solution for boaters who need a long setback to improve holeshot and top-end speed. Because it is a manual plate, it is lighter and more affordable than hydraulic versions, though height changes must be made while the boat is stationary.

Installation Tip: Because of the significant 12-inch leverage, it is highly recommended to use a transom support plate inside the bilge to distribute the weight and stress across a larger area of the transom.
