Upgrade your boat hoist with the Flat-Plate to A-Drive Hoist Hanger Upgrade Kit, the perfect solution for center mounting on wood beams. This kit includes everything you need to upgrade your hoist from a flat-plate boat hoist to a direct-drive boat hoist.
The drive pipe slides over the hoist sleeve and bolts into the driveshaft. Additional drilling into the drive pipe may be required. The hoist hanger mounts to a wood beam or wood joist using (2) 1/2 in. mounting holes on the square end of the hanger plate. It follows the same mounting hole pattern as a flat-plate boat hoist.
The kit is made of steel, with laser-cut mounting holes and two coatings available – hot-dipped galvanized or powder-coated silver. The hanger plate follows industry-standard flange mounting guidelines, and it allows easy adjustment to drive pipe supports already mounted. Upgrade your hoist with ease and efficiency using the reliable and sturdy Flat-Plate to A-Drive Hoist Hanger Upgrade Kit.
Installation:
When installed at the industry-standard vertical mounting, the mounting holes line up where the flat-plate boat hoist use to be. Horizontally mounting will require drilling extra holes in the wood beams to accommodate.

(1) A-drive hoist hanger plate
