Turtled my cuda today. My lowrance was on before the incident, but wouldn't come on afterwards. Anyone know, is it toast?

Most likely toast. I have a Lowrance on a Bass Raider pond boat and it got soaked during a 3 day rain event but was never dunked. Somehow water got inside the screen unit and I couldn't get the water out or get it to work again. I called Lowrance customer service, told them what the issue was and mailed them the unit. They tested it and replaced it under warranty. I now plan on keeping a zip lock bag over it if it is outside while raining.

Gather up your receipts and serial number and give them a call.

Mine quit after a 3hr ride home in a heavy rain storm. Left it outside in the sun for a week and it's working fine now.

I've got it covered in rice for now. Fingers crossed!

I flipped my yak and that had Lowrance HDS 8. It would not power on so I took it to Cabelas and had them hook hook it up to their display model. It powered right up. Long story short during the flip my battery got tossed around loosening the wiring. Simple rewire and I was running again. Might not hurt to check your connections.

Hmm, thought those were supposed to be waterproof. Hope it starts working again

I see you've got it in rice already. This is what I was going to suggest. I usually put my small electronics (phones and radios) in a gallon of dry rice for a week.

Just another reason to get a HB...LOL
Hope ya get it goin....

Keeping fingers crossed for that the rice works! It's saved my kids phones a couple times.
