Adding waterproofing to Lowrance Fish Finders

Recently my Elite 4 w/ GPS got splashed a bit while launching and it was one month past the warranty, so they charged me $150 for a new Hook 4 w/ GPS ($250 on amazon). It only has a 180 day repair warranty since it was a discounted replacement. I am not pleased with the customer service, but my kayak is already rigged for a Lowrance FF so I am going to give it one more shot.

I was wondering if anyone has any ideas to improve the waterproofing on Lowrance FFs. I think I will marine goop the circular gasket on the back and possibly add some goop under the two nuts that hold the cable plugs into the back of the FF. I plan on calling Lowrance first to see if doing any of this will void my warranty...

Has anyone done extra waterproofing to these? Any ideas?

Thanks

Must just be the new stuff my two older units have been completely under in the spin cycle and both work fine.... now I do fresh rinse and hang dry inside.

Let me knoe how it goes, i just got a hook 4 and  rinsed it off with the hose last week after diving, probably shouldnt do that anymore i guess

Elite 4 is pretty old yea? They're not really designed for kayaks and splashing to my knowledge. Just have to accept they have a limited life using them that way without a mod. Interested to see what you come up with. Lowrance was pretty good to me, my new hook 5 is on its way now after the same thing happening to my elite 5.

I gooped up rubber cap to seal up the unused connector port on the back of my unit.  For the card slot with the chintzy rubber gasket, I taped over it with aluminum tape which I periodically replace.  Dielectric grease on the transducer connector on occasion.  I'm mostly in salt so I usually hose down the unit before storage and have been using going strong with this set up for four years thus far.  knock on wood.

Silicone or goop the edges I assume would probably somewhat waterproof it.

Thanks that's all really helpful. I'll probably do the same

It was about a year old. If hobie is going to sell kayaks lowrance ready, shouldn't the fish finders sold at the same time be kayak ready? Hehe

Yeah I'll probably wipe it with a wet paper towel from now on.
