Bob’s Machine 100-106010 Action Series Jac Plate – 6″, 300 HP Max
Features include a large powerful motor capable of lifting heavy outboards under full power in six seconds, delivering 7.5″ of lift. It uses a one-piece design with an internally mounted pump and includes wiring harness, control switch, automotive grease fittings, and adjustable tension rods. Best for mid-size outboards on boats that require fast, consistent lifting and reliable operation. Caution: ensure compatibility with your transom dimensions and hydraulic system wiring before installation.
Bob’s Machine 100-108001 Action Series Jac Plate – 8″, 300 HP Max
Designed for larger engines or boats that require additional clearance, this 8″ unit also shares the same robust build as the 6″ version. It provides 7.5″ of lift with a one-piece internally mounted pump and includes all essential mounting hardware. Best for anglers or skiffs with bigger outboards seeking improved performance through higher engine height. Consider this option if you need extra setback without compromising lift speed.
Bob’s Machine 100-105100 Hydraulic Action Series Kick-Back Jac
This unit features a 6″ hydraulic stroke with an integrated 1.5″ lift structure, yielding a total lift of about 7.5″. It is designed to help boats navigate shallow water and avoid submerged obstacles that could damage a lower unit. Delrin rollers and bearings ensure smooth operation, and a motor tether point adds safety. Best for shallow-water boats or river runs where ground clearance changes rapidly. Limitation: built-in lift structure requires adequate spare space on the transom area.
T-H Marine PL-65 High Speed Hydraulic Jack Plate
Engineered for reliability with no welded or cast components to fail, the PL-65 is rated for V-6 motors and smaller. It offers a fast lift time and a precise rod-and-slot lifting design with self-lubricating features. Best for mixed-water use and boats requiring rapid height changes without sacrificing durability. Choose this if you value straightforward maintenance and a proven track record in salt and fresh water use. Limitation: may not support very large outboards beyond V-6 class.
T-H Marine AHJ-6VHD-DP Atlas Hydraulic Heavy-Duty Jack Plate – 6″ Setback
This heavy-duty Atlas model provides a 6″ setback with a quick 8-second lift time and a robust rod-and-slot lifting design. Self-lubricating components reduce maintenance needs, making it a solid option for saltwater and freshwater boats that demand consistent performance under heavier loads. Best for anglers and commercial users who operate in variable conditions and require dependable lift without frequent adjustments. Limitation: heavier unit may require stronger mounting reinforcement on older transoms.
Buying Guide: Key Considerations For Hydraulic Jack Plates
- Boat and motor compatibility: Match the jack plate with your engine type, horsepower, and hull design. Higher horsepower setups typically require sturdier plates in larger sizes.
- Lift height vs setback: Decide how much vertical lift you need and whether it’s paired with a setback for improved aerodynamics and water handling.
- Build quality and materials: Look for one-piece pump designs, corrosion-resistant finishes, and durable mounting hardware for longevity in freshwater and saltwater environments.
- Installation considerations: Some kits include wiring harnesses and control switches; verify compatibility with your boat’s electrical system and space on the transom.
- Maintenance and serviceability: Favor plates with self-lubricating components or easy access to grease fittings for simple maintenance.
- Maintenance environment: For saltwater use, prioritize corrosion resistance and protective coatings to reduce wear over time.
- Operational speed and control: Consider lift time and control precision to ensure quick, reliable adjustments during operation.
- Weight and mounting: Heavier jack plates may require stronger transom reinforcement and may affect boat handling; plan for mounting support accordingly.
FAQ
- What is a hydraulic jack plate used for on a boat?
A hydraulic jack plate raises or lowers the outboard motor to optimize performance, improving hull lift, speed, and handling in varied water conditions.
