Morning Mr. Trolley, on my similar vessel (same year, same model) there is a four inch square molded plastic box next to the battery switches in the lazzaret. This box has a red circuit breaker and two screw in glass fuses. These are your constant power circuits (always on)for the bilge pumps. One fuse feeds the forward pump, the second fuse feeds the mid ship and rear pump. these fuses need to be cleaned and checked on a regular basis, start there, it is most likely your issue, good luck and enjoy the boat!
