52mm Trim Tab Position Gauge
| Reads | Trim tab position |
|---|---|
| Resistance | 180–10 ohms |
| Gauge size | 52mm diameter |
| Power | 12v/24v |
| Waterproof rating | IP67 |
| Backlight | Red or yellow |
| Face | black or white |
| Bezel | black or white plastic, or 316 stainless |
A 52 mm analogue gauge that shows trim-tab position, so you can set and repeat the boat’s attitude in the water rather than guessing. It reads from a trim-tab sender across a 180–10 ohm range.
Marine-grade and IP67-rated, available in a choice of face and bezel colours with red or yellow backlighting, for 12V or 24V systems.

Fitting on 12V or 24V — and why a voltage regulator helps
A 12V system is never a steady 12V: it sags under load, rises to 14V or more on charge, and spikes as things switch on and off. The gauge sees all of it, so readings can wander with the state of the electrics rather than with what you’re measuring. A voltage regulator delivers a clean, steady voltage whatever the supply is doing — so the gauge reads consistently, the backlight stays even, and sensitive electronics are protected from spikes.
On a 24V system a dropping resistor is supplied to suit the gauge, but a regulator is the better option: resistors run hot, waste power and add a failure point at each gauge, whereas one regulator feeds the whole dashboard from a single clean supply (the 3A model runs up to 20 standard 52mm gauges, the 5A up to 38).
