I just installed a VV7 in my 42 fountain with 525's. Every time I turn the key on to start it, it will run through a scan and come up with 7+ error messages then after a few seconds it will say everything is ok. If you go in to the error history it records ever one. So there are hundreds of error codes. They are all related to stuff that is not hooked up on the engines, IE, Tank 2 circuit high, trim limit circuit high.... Is there a way to turn these inputs off so it doesn't keep recording all this garbage every time I start the boat?
Thanks,
Chad

I also would like to know.

There is a complete set up for the display. You may have to find a manual for it if it did not come with one.
Maybe your mercury dealer can give it to you.
Yes there is way to eliminate some of them.

The manual is found online. Mine did not come with one. DR is correct, just configure the parameters at apply to your condition.

I did download the manual before I installed it. If you go into the tank configuration it says there are "none" on the unused leads, but it still throws an error code when you turn the key on. I wonder if you have to go in with a merc computer and turn those leads off. I did have to have a merc dealer rename the port engine to get it to find it.
