Check GPS speed - error message

I have the smartcraft display that comes as standard with the Verado's.

Intermitantly, (usually after a bit of a blast) the warning message, see above, flashes on the display. I have gone through all the options, but cannot find the problem.

Any ideas? There must be some sort of error as it gives my peak speed as 1437kts, now whilst she's fast, not THAT fast!

I'd heard of a Zodiac Mach 2 but never a Parker Mach 2

connection problem between the GPS and the rest of the network?

Don't know why it would read a wacky speed rather than just drop out, though.

Got a solution for this problem from Barrus at the boat show.

On a twin engine set up, the speed information must only come from the GPS at all speeds.
If paddle or pitot is selected, it gets confused!
Reset and all is fine now.

I got a recorded 302 knts Max speed on the garmin down the slip at Largs a couple of years ago.

On investigating the "snail trail", it had momentatrilty lost the place and thought I was half a mile up the hill behind the marina. I guess to get there & back to the slip in the sample time for the speed calc I would need to have been doing 302 knts...... I guess my old garmin doesn't have a sanity check on it's positional error.

I've seen that a couple of times since, but not quite as spectacularly as that. Apparently I can walk at 48mph too! It's only the Vmax record that gives it away.
