T-H Marine Mini Jacker MJ-1 Cast Aluminum Clamp-On Jack Plate for Outboard Motors up to 35 HP

The T-H Marine Mini Jacker MJ-1 is a cast aluminum, clamp-on jack plate built for small outboard motors up to 35 HP or 150 lb. It is designed for clamp-on mount outboard engines and lets a long shaft motor be mounted on a short transom boat, making it a common choice for skiffs and aluminum boats. The jack plate provides a 4 inch stand-off (setback) from the transom and a 3 inch vertical offset, positioning the motor to help the boat plane quickly and improve overall performance and maneuverability.

The MJ-1 features a wide engine mounting surface measuring 11 1/2 inches wide by 10 inches high, giving secure support for the outboard motor. Its transom mounting flanges extend up to 17 inches wide, spreading the mounting load across the transom for a stable, secure installation on a variety of small boat transoms. It is constructed from cast aluminum with a powder coated finish in silver, giving it resistance to corrosion in saltwater and other harsh marine environments while keeping the unit lightweight for handling and installation.

This jack plate is intended for clamp-on mount outboard motors only, up to 35 HP or 150 lb, and is best suited to boaters who need to fit a longer shaft motor to a shorter transom or who want adjustable motor positioning for improved planing and control.
