In responce to Still's post:
Daddy told me of about the same thing happening with the V I've got when he had it.
He stopped at a light about the same time a "gentleman" on a bicycle did, as he started from the light the bilge pump activated and a 1" stream covered the bicyclist. As you can imagine, the passenger in the truck with Daddy was bewildered as to why this guy on the bike was wanting to whip both of them. It took Daddy several minutes before he could explain what happened.
The floor coolers in this boat drain into the bilge, just so you get the picture.
