mystery guage on dash panel?
 

hello all this is my first time ever in a forum so here goes... i have a 94 mariah talari z210 and in the middle of the dash panel there is an analog resetable guage that only reads while underway. what does this guage tell me? is is miles traveled or fuel burned or what im baffled thanks again in advance

There was a trip odometer and an air/water temp gauge on the dash of those Z model Talari's but i thought they were both digital. Can you upload a pic of your dash?

Welcome to the board 2005expedition! What you're seeing is the trip odometer. I've never been able to figure out what mine specifically measures, but it hooks up to the "paddlewheel" sensor on the transom by your outdrive. It's got a circuit board hooked to it on the back of the gauge.

The air/temp display is located on the side panel by the radio.
