Does anyone know how many transducers can i place thru the hull on my 330 Sundancer 1997. I have two old transducers at the moment that only do depth and speed but they have a 1 and 1/2" hole thru the hull, my new fish finder transducer needs a 7/8 hole. So i was thinking just add another hole, but my mechanic tells me you can only have 2. Some how that doesn't seem right to me. Can someone explain it to me?
 
wont matter just don't put it inline with the others.. in other words you don't want one foot in front of the other, you have to side step..LOL..
 
Your transducers will interfere with each other if they are on the same frequency. They actually detect bottom via a cone shaped signal that bounces off the bottom. If the two cones touch, it will mess up the signal to both units at the depth where the cones cross each other.

Now, if you have transducers just sitting there and not in use, no problem.
