Below Deck Variable Speed Compact Motor Electric Conversion Kit - 24V for 50ST Winch
The uncompromising ANDERSEN Variable-speed Compact Motor™ is especially developed for use as a winch motor. It is available in two versions; Below Deck, with smaller, built-in dimensions than a standard motor and Above Deck, featuring the winch mounted directly on the motor for deck or mast installation. This motor is highly efficient, with an impressive line speed and first-rate maximum load. The unit is extremely easy to install and demonstrates why ANDERSEN Products are in a class of their own.
The motor is built on an entirely new commutator principle using no carbon brushes, resulting in the virtual elimination of wear and tear. This new approach to motors also provides other advantages; including 30-50% less power consumption compared to a conventional electric motor.
Electric conversion kits are delivered mounted to a stainless steel winch/deck connection plate and have everything you need for do-it-yourself mounting including installation manual, switches and cable terminals.
Important Information
Mounting of an Above Deck Compact Motor™ winch on a vertical surface is not recommended, as it increases exposure to potential problems of excessive moisture and water ingress which could lead to damage not covered by warranty. The motor/gearbox unit of any Above Deck Compact Motor™ Electric Winch is more exposed to the elements than a below deck installation which keeps the motor unit and gearbox more protected. It is important to take reasonable precautions to protect the unit from unnecessary exposure, and carry out regular seasonal maintenance including the lubrication of the motor shaft seal. This is just good seamanship. On commercial and military vessels, it is common to see exposed equipment with electric motors and gearboxes fitted with covers when not in use or to protect them from heavy spray, etc. Equipment on yachts deserves the same proper care.
** Before ordering, please contact us to ensure your Andersen Winch is compatible with this Conversion Kit. Refer to the Winch Product Version Number when inquiring or ordering powered Conversion Kits. The production year, month and version no. [YY-MM-VER.] are stamped on the top side of the deck flange, between the mounting bolt holes. You’ll find it, when the polished winch drum is removed. **

Installed on Yanmar 4JH57 engines with Zeus Controllers - HOLY WOW power. Losing some power at top end but overall very satisfied. Will do a long term review later. Talk about power - hope to never need my generator again!
We bought these boots in 2022, and are buying new ones 3 years later. We love the design and the fact that they are easy to remove for inspection of the rig.

Complete upgrade of my Irwin 54 Sloop electrical system –
Phase 1 – Remove 9KW generator, install 30KW LifePO4 battery system, inverter chargers, battery chargers, etc. wired for worldwide shore power capability to ABYC standards. Installation made possible with guidance and support from Andre Cormier and The Yacht Rigger.
I was amazed with the product especially, the attention to detail. I was also very pleased with the help and recommendations I received from Chris Wilcher. He made the purchase very easy.
