Mo' you don't need a mechanic to do a shoot through install
It's so simple even DD could do it.
Assumptions - you have a glass boat, you have access to the bilge where to mount it and you have a puck transducer.
1) Ya want to make sure you get a good return where you plan to mount it. Such as right on the flat running surface pad. To test your signal, fill the bilge area with enough water to cover the ducer by about 2". Put something on it to hold it in contact with the hull as well as possible and take a look at your FF. Move it around to see where the best signal and least interference is.
2) Once you've found the spot, clean the area with something like dawn detergent and flush with water.
3) Take either plumber's putty or playdoh and build a circle dam around the area where the ducer will go.
4) Place the ducer inside the dam.
5) Mix 2 part slow cure epoxy to directions. Take extra, extra, extra, extra care to not mix bubbles into the expoxy.
6) Carefully pour the epoxy into the dam you've made and fill until approximaley 1/2 of the ducer is submerged. More is OK, but not needed.
7) Allow to cure for at least 8 hours or as directed by the mfg.
8) Test it out.
9) Finish the wiring.
If you get bubbles, it will interfere with the signal. Enough in the wrong spot will kill your signal. Some epoxies can be heated slighly to release the bubbles....some can't depends on the mfg and the type. Slow cure is much easier to work with and keep bubbles out, plus is stronger.
Downside to this - if it doesn't work out or you get a bad set with bubbles or poor returns, only remedy is to knock it out with a hammer and start over.....most likely with a new ducer required.
There...you're educated. And you owe me lunch.
Wannabe...
