MKIV Electric Unit 3E
A Harken Electric Jib Reefing and Furling system is a simple solution for sailors looking to add push-button comfort and safety to their cruiser. These sleek free-rolling systems are easy to install and allow crew to quickly furl and reef from the cockpit, while maintaining sail shape and optimal speed.
High-torque, high-efficiency motor consumes little power. Permanent magnet design motor gives off little heat; reduces condensation to prevent electrical shorts. Reversible drive uses a high reduction worm gear to prevent sails from unfurling under load.
Easy upgrade from the MKIV Unit 3 manual unit with the Harken Upgrade Kit.
