X 45 8.1 Indmar question

[Hspencer]

I have got an x45 with an 8.1 Indmar and have a couple things going on. We installed batteries, then every once in awhile the boat loses power and wont run over 25 mph(normally45). There are no warnings or horns.

The things going on are the gauges stop working, but then you can turn on the Nav lights and the gauges will start working again. Also, I have a SPN code of 65581 when i hook up the code reader that I have purchased.

Any ideas? Thanks for your help

What year? Does it occur after a long engine idle speed outing? Mine went into safe mode after we had it in idle speed trying to fix an ipod problem. I corrected itself after I shut down and restarted. My service manager stated their was a download fix for this problem and he fixed it at my first service.
