Well, in any case, I have 4 bilge pumps on board this boat, with the combined ability to pump well over 2500 GPH. So, hopefully, I'll never have to find out whether those fuel tanks provide any flotation!
I suppose I could put a block of foam in front of the starboard side fuel tank, I do have a little room there. But on the port side, I wouldn't be comfortable installing foam, as there is a waterbox on this side, located behind the fuel tank, and that waterbox can get pretty warm. There would have to be some kind of heat shield installed to prevent a possible hazard.
41 gallons a minute? Dang...that's like .70 gallons a second! Yeah I think you should be ok, sir.
LOL, I hope so. On the deck, there's a 500 GPH fully automatic, self-contained pump. In the bilge/engine compartment, on the starboard side, there's an 1100 GPH controlled by an electronic float switch, then an 800 GPH controlled by a switch at the console.
Then on the port side of the engine compartment, there's a siphon bilge, that is hooked to the jet pump...the same type of system used in jet skis. As the hose connected to it is 1/2" diameter, I guess-timate its GPH flow to be around 300-350, but that varies, depending on the amount of water exiting the jet nozzle, as more exit pressure equals more suction at the strainer in the bilge. So, at higher RPM, it's obviously going to pump more than it does at idle.
When I had the 2 stroke engine, there was only 1 bilge pump on board, at 1100 GPH.
But then I got swamped by a 3 foot wake from a para-sailing boat, and it flooded my boat so badly that my engine sucked water and blew a piston. When I installed the 4 stroke, already knowing that 4 strokes are even
less tolerant of water than 2 strokes, I went overkill with bilge pumps, and also designed the engine compartment so that water has to be over a foot deep on the main deck before it ever starts leaking into the bilge.
