My 96 had a paddle wheel on the transom

Is there any way to adjust the read outs? Both my air and water temps are inaccurate.

I dont think that there is any way to adjust them. You can try giving the transducer a good cleaning as crud/fouling can affect the temp reading & affect how freely the paddle wheel works. The bearings in the paddlewheel are only designed to last about 5-8 yrs. The electronics are inside the transom carrier mount so it may be that age requires the unit be replaced.

If I recall correctly, I read something, somewhere, that there were adjusting rheostats on the back of printed circuit board of the display unit. I will do some hunting and chime back in if I find something.

Just found the post with the instructions on how to adjust you air/sea temp readings. Here is the link to the post.

The company is Airmar that makes your part. It should be ST63, that what I needed for my 95. Airmar Technology Corporation » The Leader in Ultrasonic Transducers and Sensing Technology, and you can down load their catalog. I managed to find one on Ebay NOS, for around 45 buck, think they might be 75ish new. Good Luck
