    Default Transducer transom hole

    I am installing a new garmin 93sv echomap fishfinder to replace a humminbird unit. I removed the old transducer bolted to the hull and speedometer pitot input. Filled in the holes with marine tex then covered with a stern saver. The old transducer came out a hole in the transom which i got opened up and cleaned out. It is a fiberglass boat, with a thick wood transom, about an inch thick. The hole was filled solid with caulking around the cable, what a pain. Once I instal the new cable thru the hole, i plan to seal with 3m 4000. Thinking ahead if I ever have to remove, do i need to fill the whole hole solid the full thinkness with the sealent or just the end of the hole and the plastic cap/ grommet the goes over the cable? I was also considering filling in the hole with marine tex and taking the cable up over the transom and in with motor cabling, but it is a larger size hole for marine tex and afraid power cables from motor will interfear with transducer signal. Not sure how to proceed.

    Ended up just packing the hole full of 3m 4000 after talking to boat shops in the area.
