🛒  Check Price on Amazon →

In our evaluation, the Bob’s Machine Shop Manual Jack Plate stands out for its exceptional durability and performance.

It features a 6-inch setback and 6 inches of hydraulic lift, making it suitable for large center consoles and offshore boats. Owner feedback emphasizes its durability and the ability to fine-tune engine height even in rough seas. The powder coat finish and stainless steel parts resist saltwater corrosion well.

Frequently Asked Questions

What does a jack plate do for an outboard motor?

A jack plate lifts the outboard motor vertically and sets it back from the transom. This allows you to raise the engine to reduce drag and improve speed, fuel economy, and handling. The setback also helps balance the boat and improves the hole shot by allowing the engine to be mounted higher without cavitation.

How much setback do I need?

Setback typically ranges from 4 to 6.5 inches. A longer setback (5.5-6.5 inches) provides more leverage and bow lift, beneficial for high-performance boats. Shorter setback (4-5 inches) is suitable for smaller boats and lower horsepower engines. We recommend matching the setback to your boat’s design and intended use.

Manual vs hydraulic jack plate: which is better?

Manual jack plates are simpler, lighter, and more affordable, but require stopping the boat to adjust. Hydraulic plates allow on-the-fly adjustment, ideal for varying conditions, but are pricier and have more components that can fail. Choose manual for budget and reliability; choose hydraulic for convenience and performance tuning.

Will a jack plate work on any outboard?

Most jack plates are designed for outboards up to 300 hp or more, but you must check weight capacity and bolt pattern compatibility. Ensure the plate’s setback and lift range suit your transom design. Some boats may require transom reinforcement for heavy plates. Always verify with the manufacturer.

Do I need to reinforce my transom for a jack plate?

It depends on the plate’s weight and your boat’s construction. Heavy hydraulic plates or those for large engines may require reinforcement, especially on older or lighter boats. Manual plates are lighter and often bolt directly. Consult a marine professional if unsure.
