Patching tranducer screw holes

[High Bidder]

I am changing transducers and have to patch the seven screw holes from the previous transducer and speed wheel. Can I use Bondo to fill the holes then put a gel coat over it? I'm not concerned with color match as it is below the waterline. I can't do anything immediately anyway because with the heat wave we had today the bottom of the hull is sweating like crazy.

Hi !

I would use Marine-Tex . If you have a white hull you won't even notice the patched holes after you sand it.

Good Luck !

Thanks for the advice. This changeover from the Lowrance unit to a Humminbird unit is getting complicated. I decided to get just a 778 sonar because I use a separate GPS chartplotter unit and sonar alone was less expensive. Or so I thought. Since it is only a sonar I had to buy a special Humminbird cable to update the sonar system program. Then I had to buy a a adapter to connect the Special Humminbird Update cable from the old outdated 9 pin serial port they still use to a USB port to connect it to my computer. Then I had to buy a transducer extension cable because the Humminbird cables are alot shorter than the Lowrance cable. After it is all said and done I should have bought a sonar GPS unit which has a SD card for updates and stayed with Lowrance who does not short you on transducer cable length. I'm glad I started this operation long before I actually need it. I hope when this is all done it is worth it.

Jack's right.....Marine-Tex expensive but worth every dime...This stuff will hold when applied under water...This stuff is all that holds our old Trophy together
