Default Simrad 3g warning !!!

According to Navico you can NOT flush mount the 3g to your hardtop !!!!!!!!!!
It can wick water up inside the dome. That is what happened to mine. Navico stood by me though. So I wanted to share this with everyone.

What's the difference in flush mounting on a hard top vs bolting it directly to an aluminum plate like most soft t- tops are? ;?

I think the water got in there some other way.

I guess it depends on how old the unit is. If I knew about this before I would have dismounted the unit and looked for a nickle sized hole on the bottom. If you find it , put some spacers between hardtop and unit.

I think it would be better to call Simrad than Navionics

The water intrusion problem affects 4G units as well. My 4G failed and had about a cup of water inside it. But mine is mounted on a 6" riser, so the water did not get inside by wicking.

Simrad sent me a new one. Apparently the case design or seal is now modified.

the problem was a bad bleeder seal. the seal was supposed to let condensation out but not let outside water in. condensation was not draining, leading to the dome to fill up with fresh water (condensation). even in a saltwater environment, the dome would fill with fresh water only. problem has been acknowledged and fixed and Navico was very good with replacing mine- no questions asked, shipped same day, easy swap out.
