catalina 25 tall swing keel Manahawkin bay
Ive just by way of a gift become the owner a Catalina 25 swing keel older , My Question this boat has a electic winch for the Keel it seems to have no controls for the motor on the main wiring harness i have found a switch with a round know that turns 360 each way you turn it it has a hot and ground coming out of it . I dont know what this is for there is a hole in the back the motor cover on the winch im assuming this must be the switch anyone else come across this ?

The keel is current up and being held so via a screw drive threw the spokes of the winch wheel
Not exactly that greatest looking rig.

Im also looking for a furling genoa 150 110 130 Furling system in good shape
