    Does anyone have a transom mounted transducer on their boat? If so, how did you run the connecting wire through the transom with the swim platform above it? I have a 230 Select and I have tried the shoot through the hull transducer and that didn't work. I would like to mount the transducer in order to get water depth info to my chart plotter/sonar. I'm just concerned about drilling a hole through the transom. Thanks.

    I did. Drilled hole above waterline, but below swim platform.
    Siliconed the heck out of it, and used stainless steel cover to cover the hole. No leaks detected yet.

    +1 for SloBurn comment - I need to re silicon after I installed my new swim platform.

    Same for me. Used the life seal silicone above the water line but below the swim platform with no problems yet. I Have a small Garmin unit that works great

    Thanks for the feedback. I was thinking of mounting it to the first horizontal step on the right as you come off of the bottom V. Then bring the wire through above and to the right of the outdrive. That would be the highest point out of the water. Would this work? See the photo. Sloburn, where did you find the stainless steel cover? transom.jpg

    This is the same 215 as mine, but a stock photo from swimplatform.com Mine is in this exact location. I am not sure if the first chine/step is the best location. You could get prop wash or some disturbance from the outdrive.

    I also added one of these when I put the new swim platform on and filled the previous holes with six10 epoxy.

    As far as the SS cover, Perko makes them. They are called a 'clam shell ventilator'

    This is exactly where I mounted mine. Works well most times, some loss of bottom when in murky (bay) water, but it always finds bottom again in seconds. Clam shell link below.

    Sternsaver is great. Here is my install of the FIshhawk transducer on my 330.

    I went back to the boat today and examined the mounting options. Does this look like a better mounting location? I could then route the wire up into the outdrive recess and take it through the hull into the open area to the right.

    I like that better, that is exactly how mine was done.

    It is a very clean boat. I just bought it in August. I searched from FL and the gulf coast through the rest of the eastern half of the country and ended up finding it 5 miles from my home.

    I mounted the transducer and routed the wires with no problem. I took the boat out on the ICW yesterday and couldn't get it to work. I pulled up and called Humminbird tech support while I was on the water and they diagnosed that I had a bad transducer. They're sending me a replacement. The saga continues.
