I found Serenity sitting lopsided in the water after the recent storms and snow. The starboard battery compartment was flooded. On pumping the water out, the battery seemed to have survived. I checked the wiring and none of the float switches on the automatic bilge pumps had been connected so the pumps couldn’t operate automatically. Rewiring is in progress. Additionally, the batter compartment pump was siezed and needed replacing. Although the new pump is a different make, it sat in the old cradle which saved some work.
