Would like to ask a rather odd question about the water pump on our Jetskis. This has been bugging me all these years and may need somewhere who is pretty technical to help me out.

In all brochures and tech specs we see a claim of about 1500 lbs of thrust ( example ) for the jet pump. Does this mean that

1. the pump actually pushes out 150 gallons of water per minute ?
2. or is another formula is used, how many gallons will there be per minute for the 260x ?
