This is the same problem I run into where ever I go. Why do it rather than how to make it work. Thanks for your time.- Dan Steill

It is a water pump designed to move water, not propel a boat. I am just seeing if its use can expanded to another aplication.- Dan Steill

in expensive single stage centrifugal pumps hhave been tried. I am not sure about multi chamber.- Dan Steill

Right now, no matter the size or shape of the boat, if the stream of water exits at 7mph, the craft will not attain that speed reguardless of size. This is precisely the problem that has not been conquered in attempting to use this type of centrifugal pump. I thought that a re-visit might be...- Dan Steill

Sir, I Am Another Boat Person Trying To Re-invent The Wheel. I Understand That. The Lol After My Statement Was Show Understanding, Not Distain. I appreciate all the assistance I can get which I feel tthat have received so far. what specific spec on the pump do you need as make and model...- Dan Steill

In 12"x4" pipe, 75 inches³' 1728 inches³=1 ft³, .04ft³ of water in the pipe. If 50m³ water per hour, 10.5 ft/sec. If right = 7mph... I THINK I need 3 times that speed or 20 mph...- Dan Steill

263 g per meter³ gives you 26300 ghr, 7.3 g/sec, 65.3 lb/sec. That is coming out of a 4inch pipe. Even with 50% efficiency, that's over 30.0 lbs/sec. At this number, can you compute the velocity? With the 4 inch outlet pipe 1 ft long from the pump?- Dan Steill

I can be ridiculed in boat forums as well! lol. in the next 20 yrs, with global warming etc., living on the water isn't a bad idea. doing it cheaply and with a small footprint is the goal. a pump like this can be acquired for a reasonable price, a 10th of the cost of a normal proposition...- Dan Steill
