To identify your IDEAL Windlass first look for our nameplate. This plate is located on the gear case of your windlass and tells you the Model and Serial numbers of the windlass. If your windlass is vertical the gear box and motor are  below deck.  If it is horizontal your unit is all above deck.

Other ways of identification include, knowing the size and brand of boat,  the diameter of the deck plate and number of deck bolts (if vertical) or if horizontal whether the motor is exposed or enclosed in the gear case.
