Bob's Machine Shop - Gen 3 Extreme ACTION Series Jack Plates

Get the Right Jack Plate for the Best Performance

The Bob’s Machine Shop Gen 3 Extreme ACTION Series Jack Plate is designed for high-performance outboards that need strong, precise hydraulic adjustment. The Gen 3 Extreme builds on Bob’s proven jack plate design with a lightweight one-piece aluminum and stainless-steel construction and an internal hydraulic pump that keeps the hydraulic system protected inside the boat.

The Extreme ACTION Series gives you precise hydraulic control over your outboard’s running height, making it easier to fine-tune the motor for your specific boat and conditions. Adjust engine height on the fly to improve performance, optimize propeller bite, increase shallow-water clearance, and get the most from your outboard.

 Frequently Asked Questions 

  • What makes the Gen 3 "Extreme Action" different from standard jack plates?

The Gen 3 Extreme ACTION is built for larger, heavier, high-horsepower outboards, supporting up to 550 HP and 1,200 lbs. It also features an integrated hydraulic pump and supports motor mounting widths up to 15".

  • What hardware and components come included in the box?

The box includes the Gen 3 Extreme ACTION jack plate, wiring harness, relays, and rocker-style switch. The hydraulic pump is integrated into the jack plate, so no separate pump or hydraulic hoses are required.

  • How much vertical lift does the Gen 3 Extreme Action Series provide?

Yes, you can mount shallow water anchors such as Power-Poles or Minn Kota Raptors using compatible side-mount adapter brackets. These brackets bolt directly to the sides of the jack plate structure without requiring you to drill additional holes into your boat's transom.
