Hello to all, and thank you in advance for any help. We recently purchased a 1998 Fisher Marsh Hawk 170, with the good fortune of all the accompanying manuals. Unfortunately, some of the info is vague. Our livewell has a Marpac 7-2214 aerator, (750 gph), which we have learned only primes when the vessel is traveling in reverse. No problem, since we go backwards off the trailer every time. The control for this pump is located on the helm. There is, however, an additional switch on on the bulkhead starboard of the helm labeled "recirc -- empty -- auto". The manual shows a secondary pump for this remote operation, but we have not been able to locate it. It appears as though the cable from this switch is connected to the Marpac we located under the bench seat. Does this pump have dual capabilities? Naturally I had to play with the switch, and on only that trip we ended up with a bilge full of water. Bilge pump works! :lol: Thanks again!
