It is part of T-H Marine's HI-JACKER Z-Lock series, which uses a Z-Lock design with matching slotted extrusions that lock the side plates in place, eliminating the side slippage and lateral movement common with conventional jack plate designs. This rigidity keeps the outboard positioned correctly under load, particularly at higher speeds and during hard turns.\u003c\/p\u003e\u003cp\u003eThe JPZ-4 is rated to handle all V6 and V8 outboards up to 300 hp, making it suited to a wide range of performance and bay boat applications. Height is adjusted from the top of the jack plate with a single center bolt adjustment point, and the unit provides 5 inches of vertical adjustment to fine-tune engine height for the boat and running conditions. As a manual (non-hydraulic) plate, it has no pump, reservoir, or lines to install or maintain.\u003c\/p\u003e\u003cp\u003eSetback determines how far the engine is moved aft of the transom, and the JPZ-4's 4 inch setback is the shortest option in the Z-Lock lineup, which is also offered in 6, 8, 10, and 12 inch setbacks. Because setback affects handling and the manufacturer notes that adding a jack plate can affect boat performance, checking with the boat manufacturer or a local dealer for a setback recommendation before installing is advised. Mounting bolts and hardware needed for installation should be confirmed at time of purchase.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e T-H
