This two-piece jack plate uses 3/8 in. aircraft aluminum with a natural aluminum finish that resists corrosion, and it fits V-4 and V-6 engines up to 150 HP. Dual stainless steel adjustment rods, stainless steel bolts, and brass nuts help keep adjustments smooth and help prevent galling, while the design allows full tilt with dual steering for practical rigging flexibility.
