Hello Fellow Hunter Owners,I reciently purchased a 1978 Hunter 30, and while it was a one owner boat it was used as a storage shed tied up to their dock for several years and was filthy. As I cleaned it out and started investigating my new water front condo, I noticed a valve in the port side storage locker in the V-Birth. Does anyone know what this is used for? There is also a pump lever which I think is used to pump out the waste holding tank?Additinally there is some sort of round module attached to the hull under the bathroom (head) sink cabinet with some wires coming out of it. Any idea what this might be?Thank you to anyone who can assist with these mini mysteries. Tom (Wavedaddy)
