PiranhaMax question

[PerryC]

Heya,
Offhand, I would guess the transducer install. The only hulls I know of that have problems if they're not prepped right are the older malibu kayaks like the eXtreme with the foam in the hull. Most all other brands without foam do pretty good as long as the place where you install it is under the waterline where water is constantly against the hull to get a signal through.

If it were me, I might take the transducer off and scrape away any remaining silicone from it. I would try the vaseline again, and if all was good with that, I would clean the vaseline off the area where I test mounted the transducer/puck at, and I would remount it. I would try a different adhesive like Marine Goop though. I'm not an adhesive expert, but I used Goop more than a few times with good results. If you want, try that and please let us know how it works out for you, Good Luck,
Perry
