Trim Sender Units
The trim senders are no longer sold individually.
The Port switch is the Trim Limit Switch. This limits how far up the drive will trim.
The Starboard switch is the Trim Level Sender switch. This sends a signal to the trim gauge.

If one or the other malfunctions, you will need to get the entire Kit.
The Kits comes with both senders. The senders are pre-wired from the factory
with new wires.
Mercruiser did this because bad wires were the leading cause for switch failure.
