Transducer question?

I'm having a problem with my fish finder. My transducer is mounted on the transom, but i'm getting noise from the prop. I mounted it according to the instructions. My main question is what kind of finders are you using? I'm using an eagle finder and have a mercury outboard on the boat. Thanks for any help.

You know all about being cheap huh?

if you hook it up to its own battery it will be fine. cheaper units due not suppress the noise.

which side of the boat did you mount it on?  A transom trandsducer should always be mounted on the starboard side (right side) your prop rotates clockwise this pushes the water to your port side and if the ducer is mounted there it tends to pick up noise.  Be sure you didnt mount it in the way of any chines in the hull that may cause noise as well.
 
Did the unit come with the small magnets that go around the transducer wire to supress noise?  If not might want to look into them if you have it mounted correctly.
 
As long as the unit is getting its recomended voltage it should not matter how it is hooked up (although it is best to hook up your electronics directly to the battery)...
 
 

When you say noise are you talking about clutter on the screen that may be caused from the prop and air bubbles. If it's from that you're need to try and relocate it or the sensitivity will need to be adjusted at the unit. If its elec. noise try a filter, from a place that does electronic equipment.
