I have a triton tr20. I'm thinking about mounting my 998 transducer right in the middle right below jackplate. Right below this is a small step which includes 2 water intakes for live well. I'm wondering if these 2 intakes will mess up the graph readings. The intakes will be around 3 inches in front of the ducer and 3 inches below. Sorry for the long post. I just want to get this wright. Thanks....
