Hello Everyone, My wife and I purchased a used 2008 Sea Ray Sundancer 290 which obviously has a head system and holding tank. I read the manual in Section 7, Step 1, which says to "Turn ON the DISCHARGE PUMP breaker on the salon DC distribution panel and open the waste discharge seacock located on the bilge floor." The problem is there is no such switch or even anything remotely close to discharge pump. The 2nd step says, "Operate DISCHARGE switch at the WASTE SYSTEM CONTROL area on the main distribution panel." Again, there is no such switch. Can anybody help me understand how to operate the macerator system? Please and thank you?
