Just curious if anyone knows what a stock 1990 - 650 bilge pump is for GPH ? When I put my finger on the tube end , I can feel air pull but just barely. I will probably put a regular bilge pump in regardless but just curious.
There’s no spec, the flow rate depends on throttle / speed as to how hard the Venturi pulls. Through that small line, maybe 1-2 gallons a minute so 60-120 gph when moving along.
