If you have the old Motorola you will see two wires on the regulator. One goes to coil+. Another will be grounded on the alternator case. There might be another marked "aux". All of these will come...

The MMI pumps are bronze or red brass; I'm not sure. In any case yellow brass is fine in the pumps. The real issue is problems in the expensive castings (head, block, manifold) that are not easy to...

Couple of things. Your alternator clearly has a regulator appended, whether it is being defeated thru improper wiring is another question. Mixing battery types is bad news on a boat - especially if...
