Problem with GPS/Zero-Off! Pls help

[Snowman8]

Just a thought, I don’t have a surf model and I don’t know anything about the zero off system but I use a GPS base station and rover every day at my job. Where is the GPS receiver located? Is it possible that something or someone is blocking its view to the sky at times? All it takes for my rover to drop the satellites for a few seconds is to run my hand over the receiver head. Once it drops the satellites it takes a few seconds, sometimes up to a minute to regain signal and be fixed to the satellites. I know the Trimble GPS system that I use and what the boat uses are two entirely different systems but the principle is the same as they both need a signal from satellites.

Happy 4th of July! Just to give you all an update: David’s replace the Zero-Off GPS antenna and I returned the boat to Eufaula on July 2. Thought all was good, but each morning and a few times during the weekend the Zero-Off would lose power completely. Sometimes I would tap the front of the zero-off and it would turn on and sometimes I had to jiggle the wires behind the zero-off to turn it on. I have posted the photos/videos for Davids & Cobalt. I’d like Cobalt to come fix it. Great weekend otherwise and I love the boat, just dont want to worry about it working when I take people out.
Here’s a link to the videos of the issue if anyone is interested:

Update: 7/28 - I brought the r5 back to Davids in OKC Monday and they are replacing the Zero-Off as it has a short in it causing it to lose power once in a while. An unrelated issue occurred this weekend though - the right surf tab actuator broke rendering the tab useless and broken...it was just hanging there so I had to tie it up with a rope. Apparently its a fairly common thing - who knew! So they are repairing that this week as well.

There were several members who had issues with the first gen surf tabs, but haven’t heard anything about it in a year or so. Now that Malibu owns them and they are installing Surf Gate I doubt it will ever be an issue again. Hopefully the dealer fixes it under warranty.

Update: David’s in OKC has been great to work with. I just wished there was someone closer to Eufaula lake or who would come out to the lake for service. The actuator on the surf tab was replaced as well as the zero off. Both working great now. We’re on the lake this weekend with a bunch of kids so hopefully it goes smoothly!

Glad to hear you're all fixed up. Cobalt buys quality brands of components to build their boats, but the components are often boutique items with a limited number of providers and small production runs. Glad to hear they continue to stand behind their vendors and got you fixed up.

New 2019 R5 Surf, have had 3 occasions where I get a GPS SIGNAL lost, Wake surf disabled” when the Garmin has full gps signal. It goes in and out of GPS signal, rendering the boat totally useless. I turn off the battery and reset the system and sometime it’ll work for a while. Also, The zero-off won’t hold a steady speed, it surges +|- like 0.8mph which makes surfing impossible so I have to use the rpm setting. I updated the 7607 garmins to software v19 from v15 but that shouldn’t be the problem. Last time it happened I had a boat full of kids and sat there for 45 minutes while I factory reset the garmins and set up the screens. Thank goodness it worked after that, except for the speed cruise control.
Please let me know if anyone else has these issues or maybe how to trouble shoot.

Hey Fin, thanks for your note. On your Zero-Off when you set a speed like 10.5mph does it hold there flat exactly or does it vary up and down from 10.5 a bit? Ours just goes up to like 11.3 then sown to 9.8 then back up to 10.5 and so on...just doesn’t seem very consistent but I’ve never used one before.

Hi mjmyers,

I have the exact same issue. Same boat! Did you get the problem resolved??
