A couple of trips ago this piece fell off the bottom on the console. I have no clue what it does but it hasn't affected anything at all. All the gauges are working (minus the speedometer, just a crimped tube). I was thinking it was a sensor alarm or the in-dash flasher that never works. The boat is a 1995 ProCraft Dual Pro 210 Tournament Special Anniversary Edition if that is any help. Thanks in advance!

My best guess is that it's a capacitor that controls the live well aeration cycle.  On the other hand, it could be a ferzenburg wankle, which would control the deflection of your flazexwan.

we should have a 'best of' section...and i give this thread a vote 

It's either a flux capacitor or a continueum transfunctioner

I believe it slides over the backside of one of the gauges. It's meant to keep the wiring/electronics protected from the elements. The two pieces of metal  on the side should hold it in place so the gauge itself don't fall out the front. Or it's a flux capacitor!!

It's the rear casing of your flasher, which should now just pull out of your dash.  If  it's a flux capacitor casing, sell the boat at once before both of you disappear, and you end up working as a ticket booth clerk at a drive-in movie showing the newest Roy Rogers film.

I guess most of ya'll are too young to recognize the outer shell of an old in dash flasher sonar.  Looks to me like somebody pulled the guts out of and old flasher and left the housing in there.

 

After looking at you third picture, I see the front part of the flasher is still sitting in the dash, what you have is the cover was on the back side of the dash that the internals to the flasher went in.  I guess that's why it don't work.

I hope that it is not a flux capacitor    My initial thoughts were that it was something to do with the flasher. Since the flasher didn't work that is why the piece falling out never affected anything. Thanks guys!
