Wish everyone's having a fantastic season. My boat came with an Atomic 4, from posts online regarding zinc anodes i've learned that it is an inexpensive but necessary part, similar to spark plugs. Unfortunately engine diagram in manual doesn't show a heat exchanger nor location of the zinc anode. The PO killed himself about 6 wks ago, having failed to keep a log on engine has made me anxious because i can't find the zinc anode to replace and don't know if it is better to not use engine for rest of season. Why doesn't the manual show a heat exchanger and location of zinc anode?
