Hey guys my trim gauges aren't working anyone have any laying around???

Could it be the sending units?

The gauges very rarely fail. Do some more troubleshooting before you buy gauges.

what should i look at...

what dog said

Not too familiar with the electrical indicators. Probably some type of electrical sending unit on the hinge pin part of the gimbal ring (? starboard side) with wires attached.

Diddo ! Round Plastic covers near gimbal ring on drives. These hold a gear unit for electric trim gauges.

any pics.....is it inside the engine bay..

Would be on the outside transom assembly at the hinge point of the gimbal ring (horse collar). Probably R or starboard side.

On the gimble ring outside the transom

Numbers 5 and 6 in the illustration- 5 is incorrectly labeled as a screw. One is the trailer limit switch, the other is the sender. Do the guages swing when you turn the key on??
