I have had an issue of the gypsy not engaging when dropping the chain. This is not a fouled chain as the problem exists with the chain released from the gypsy and it is free of all load. The solution was running the gypsy up without chain as the anchor was already stowed, and then running out. Whatever was sticking was cleared and it then works fine. As soon as the windlass has not been used for a week or so the problem returns. The maintenance instructions make no reference to the oil sight and I have not checked it in 9 years. Anyway the oil level is almost at the top of the glass bit looks quite brown. It only took a small amount to top up. SAE 90. How long should the oil last and could it be causing one of the pawl's to stick? How often should the oil be changed? Any experience would be appreciated.
