[QUOTE="PSG-1, post: 251263, member: 6937"] 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 [i]less[/i] 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.
