OMC Trim Sensor

[McGR]

I put a CMC power trim on my motor last year. My boat has an OMC trim gauge. I'd like to put a sensor on my CMC unit so I can determine my trim position. There is a fair chance I could make my own sender if needed or possibly I could retrofit one from an OMC trim unit. However, first I need to know what OMC used. Was it just some sort of resistive device (potentiometer etc.) or something more exotic. Anyone know??

Nothing more than a pot sealed in a mountable case with a spring loaded arm that was pushed down by the swivel bracket and a long piece of light cord to run to the tach. Don't remember right off the top of the gray cells what the pot's range is.

Thanks OBJ, I figured it was probably just a pot. So... anyone know the range??

Re: OMC Trim Sensor

If you want the easy way, go to the panthermarine website - they have a universal sender. I've posted on it before. It really is a versitile and robust (strong) design, high quality. Includes gauge.<br /><br />Looking at my own OMC sender - I don't know if you could adapt it to a CMC unit. I'm almost positive you wouldn't have any problem adapting the panthermarine unit.<br /><br />By the way, don't CMC make sending units for their TT units?<br /><br />If you want to do it yourself with your OMC gauge, and don't know the resistances involved, the teleflex websites have that info (because they make a gauge that works with an OMC sender, therefore telling you what your sender needs to put out).
