f4b-11 model 10-24690-01 to be specific.
here's a url of the specs on the pump. http://www.aquafax.co.uk/pdfs/Sect10J.pdf
It's ignition proof. Anyone have experience with these pumps or this brand? I am setting up a ballast system and I think I may have a lead on some 1+ inch 12v actuated ball valves mad flow! :-D I already have a lead on some pretty awesome mega flow spring ball check valves if I go with aerator pumps for evacuation.
They also make these monsters! 1600gph http://www.boatfix.com/shop3/store/listItems.asp?strSearch=189-1600B
I know jabsco is like the de facto but is it worth looking @ other suppliers? The reversible "ballast" pump above is 9-12gpm where the ballast puppy is like 10 and double the johnson's list price.
