"waterproof in accordance with IEC 529 IPX7. IEC 529 is a European system of test specification standards for classifying the degrees of protection provided by the enclosures of electrical equipment. An IPX7 designation means the GPS case can withstand accidental immersion in one meter of water for up to 30 minutes. An IPX8 designation is for continuous underwater use."

I have a base mount cap that adds protection to the terminals after the head unit is removed.... when i use it. Fresh water and dialectic grease. If your really anal, disconnect the battery after you remove the head unit.

I hope my old one fits the new one


My gps(garmin76) is on another mini-ramm mount (left side). I like the ram mini rams because they are not too heavy, adjustable and removable. They do not handle saltwater very well and will corrode in about 3 years, but WTF can ya do? Eventually they will come out in graphite.

I've also added strps to both hatches so they are connected while open. I'll eventually post pics when I'm done with the upcoming retrofits. I'm moving and adding two additonal flush mounts behind the seat. I'm installiing a thru hull pump to the external bait tank.
