I'm replacing my current depth finder and I have a question.......
I want to install the transducer for the finder inside of the hull instead of outside like my current setup.

Does the '01 sportster have a pre-molded in hull mounting place?

Some boats do, some don't. If it doesn't, you'll see me floating out in the middle of the lake testing good read spots on the hull.

Thanks in advance.

I haven't heard of the Sportsters having any pre-molded place for a transducer. The best you can doo is like you say, float around with the ziplocs full of water and find the best spot for your thru-hull. In hindsight, I should have done the thru-hull instead of the transom mount.

Why? I wil be installing mine soon and want to know all the good stuff..........I bought a Cuda 240s.

2 reasons- On my twin, I haven't been able to find a good position on the transom where the transducer is consistent in readings. Too much turbulence from the pumps. Secondly, it would have eliminated the extra holes being drilled in the transom.

Well I installed the depth sounder on Friday, tested it on Sunday and was completely happy with the install and performance. I placed the transducer just ahead of the carbs in a low groove section in the hull, I did all the usual prep work myself as far as testing, sanding, mounting and running the cable.
I used a norcross highspeed depth sounder using the supplied dual purpose hull transducer, some in-hull boat setups require you to purchase their higher end transducer which gets installed in a mineral oil tank to avoid interference, which is just as simple to install. Here is the product I installed:

Mine is a dry setup and is working great even at wide open throttle.

The display fit easily into the dash right behind the steering wheel, on a sportster this is empty, on the dual engine models, I believe it is where the fuel gauge is normally located. I powered the unit off of the bilge hot wire and grounded it just the same. (yes I know the draw from the bilge switch can cause low voltage to the depth finder, but it didn't effect it and when doo you ever run the bilge, only when your sinking!)

Benefits: None really, it's more for interest, by the time the low water alarm goes off, 3ft is the lowest setting, you are probably asking for a rock in your pump because the water level drops to 1ft before you know it. But placing the transducer in the hull has a cleaner look, works better in high speed situations and you avoid drilling in the hull and you will never knock it off beaching or trailering your doo.

I'll take some pictures when I have time.

Next project(s): a power block for accessories so I can wire projects like this properly and cleanly and then a am/fm/CD player.

Doo you later!

Nice... I look forward to seeing the pics.
