Do you not have the single pop out button in the middle at the top of the main breaker panel in the port cockpit labelled Windlass ? It’s not on either lh or rh bank of rockers but in the middle , see pics bearing in mind mine is 1996 user manualThere are some apparent differences. I have no breakers labled anchor on the dc panel in the port cockpit locker nor in saloon main panel. In the anchor locker is a sealed relaybox and the two
foot switches. There has to be an overheat breaker some where but yet to find it.
The bow thruster has a breaker and fuse on the port stringer next to the batteries and solenoid on the forward engine room bulkhead in front of the port engine. Looking at the SeaRay schematic on page 12.40 the malfunction is likely either the solenoid...not sure how to test..or the main switch which does not have a part number on the schematic. Will update as progresses.
