Hull #4 was blessed with a Perkins Perama M30/M25 by a previous owner. If
anyone out there has any experience with these 3 cylinder babies, where are
the zincs for the raw water circuit? The heat exchanger seems to be a tube
through the fresh water reservoir with rubber couplings (3" to about 1"
unions, approximately) on both ends- from pump, and to exhaust. No obvious
zincs around the pump or the reservoir/heat exchanger. A disaster waiting
