evins i also have a pelican 10e and love it as far as mounting the finder i mounted the transducer to the tolling motor and and the head unit i actually zippy tied it to the top of the trolling motor that way when i take the trolling motor off everything was off and protected instead of worring about ripping it off the bottom when dragging or loading the boat . and i just wired it right into the power leads on my trolling motor so when i hooked the power up for the troller also had power to the finder . if you need pics i can try to get you some up on here but can't make no promacies.... lol.
