Trojan Gauges 1970-1980

From 1970-1980 -- Trojan used AC-Delco gauges. Occasionally, some pre-1980 Trojan F-Boats like the F-30 (1979-1980) used Datcon gauges.

Problems tend to occur when the rules below are not followed. This is the often mistake of a marine technician who is inexperienced or unaware of how AC-Delco gauges and senders work together. Typically, an owner notices a gauge problem and assumes it's an issue with the sender. The sender is replaced with an off-brand / non-AC-Delco sender -- only to find that the AC-Delco gauge readings are incorrect, or the gauge is not working at all.

Here are some of the basics of AC-Delco gauges and senders:

1. You can identify a AC-Delco gauge by its tin backing. AC-Delco gauges do not have plastic backs.

2. There are two types of AC-Delco gauges - a single station gauge and a dual station gauge. AC-Delco gauges are also stamped as 'Single' or 'Dual' on the side (see photo)

3. Each type of AC-Delco gauge has a single sender. For example, AC-Delco fuel gauges must use a AC-Delco fuel sender. The same applies to engine temperature and oil pressure gauges. Note: A AC-Delco sender will power either a single or a dual gauge system.

4. Trojan used either white needle or orange needle AC-Delco gauges

5. You cannot use a NON AC-Delco gauge with a AC Delco gauge. For example, you cannot change the flybridge gauges to non-Delco without change the lower station gauges as well.

At Beacon Marine we have some AC Delco single and dual gauges.

NOTE: Senders for fuel, engine temperature or oil pressure are no longer available. WE *DO* have oil pressure, water temperature and fuel gauges that's a close match with the look of the Delco gauge. We also have senders for the oil pressure, water temperature and fuel.
