BH-45 – 4,500 lb. Deluxe Flat-Plate Boat Hoist


The BH-45 – 4,500 lb. Deluxe Flat-Plate Boat Hoist is made up of an Elite 1 HP painted electric motor with base and a 6,500 lb deluxe gear plate assembly. The Elite 1 HP Painted Wired Boat Lift Motor is a single phase, dual-voltage motors. It comes from the factory wired at 220v, but a licensed electrician can convert the wiring to make it a 110v electric motor. The motor is built from rolled steel. The NEMA 56 shaft is 0.625 inch thick and 1.88 inch extruding from the motor housing. UL Recognized (C-UL-US). It uses a capacitor to start.

TENV (totally enclosed, non-ventilated) housing. TENV housing prevents dirt, insects, and water from entering the motor. 15 minutes maximum runtime. Includes 1 inch long x 1/4 inch wide keystock, colored T-wires, easy-to-follow wiring instructions, BH-USA equipment guide, and wiring instructions. Depending on your preference, you can select a maintained (lock-on) or momentary (spring-loaded) drum switch type. The in-line GFCI has a built-in test and reset button.

The Extended Block Worm Assembly has a 2-inch bearing block, a worm on a driveshaft, and an aluminum housing with 1/4 inch grease fittings. Attaches directly to the gear plate. The assembly has standard flat-plate mounting holes. The assembly is fitted with standard flat-plate mounting holes Factory assembled. Blocks are fitted with flange bushings. They have 1/4-inch grease fittings, which can be accessed easily.

The 6,500 lb. Deluxe Gear Plate Assembly includes the 10-inch aluminum die-cast hoist pulley, 96-tooth cast iron worm gear assembly, extended block bronze worm assembly and 34-inch drive belt. There are no steel-on-steel moving parts. It has been assembled and tested by the manufacturer. The 10 in. Aluminum Die-Cast Hoist Pulley is made from an aluminum die-casting process. Over 15 years of use on BH-USA Flat Plate hoists. They are much stronger in marine environments. They will not swell or bend. The belt-gripping technology on the inside of the pulley prevents belt slippage. Compatible with any known flat-plate hoist. Resistant to warping. Designed to fit drive belts better. The bore is 3/4 inches. Accepts belts up to 1/2 inch.

The AX-34 is a 34-inch drive belt that is compatible with all flat-plate boat hoists from BH-USA. This belt is the perfect length to fit around a 10-inch hoist pulley and to be able to attach it to a 2-inch motor pulley. As the motor’s driveshaft turns, the pulleys turn the belt in order to complete the movement of the hoist.

Deluxe Series feature cast iron 96-tooth worm gear assembiles with extended block bronze worm assemblies and up to 1 HP motors.


Maintained (Lock-On) is a cam rotary switch that stays in place when you turn the handle to either the up or down position. It will continue to move until the handle is moved back to its resting position.

Momentary (spring) must be held in place. Once the handle is released it “springs” back into the rest position.

You are able to distinguish between the two cam rotary switches by the markings on the box. If there are arrows between the positions, it is a momentary switch. If there are no arrows, then it is a maintained switch.

You should never use the same materials (steel-on-steel or bronze-on-bronze) on flat-plate hoists.
When wiring or rewiring electrical components, BH-USA recommends hiring a licensed electrician.
