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

Thanks for the reply. I did a little research on the Hummingbird website and they recommend to NOT use silicon as it gives inconsisitent readings. I guess I proved them right. I asked a local boat supply place about Goop and they didn't carry it but said they had silicon. I assumed that is what the Goop was. That's what I get for assuming. I am going to remove the transducer tommorrow along with all the silicon and try again. What type of material exactly is Goop and is it removeable? Hummingbird recomends a slow set 2 part epoxy. I didn't really want to use that as I figured it would be much more permanent (in case I screwed up or it wouldn't work right).
