I have a 2006 38ZR twin 525 EFIs. (you may remember seeing this boat at the Javits or AC boat shows in Jan of 2006)
I was lucky enough to buy the show boat and love every minute of it.
This year my first problem(s) showed up.
Main GPS (between the 2 tachs) registers only 5200 -at any speed.
When engines are first turned on GPS first registers 4600, then zeros itself out (self diagnostic?), then jumps straight to 5200 and sticks there.
(When running at any speed, if I hit the tattletale, the needle zeros out for 2-3 seconds then jumps back to 5200). The tattletale does not record last high speed (I guess this would be obvious??)
Before I start ripping the console apart, does anyone have any suggestions as to causes and a short "to-do" check list of what I should be looking for.
Has anyone else had this problem?
(not sure if related, but the same weekend, my stero went out and also does not work)
Thanks
