You will also have higher frictional losses with lay flat then a smooth bore harder suction hose ( especially on sharp turns where the lay flat kinks slightly). Other things to consider include the max depth you are dredging, how high you are pumping the material up to the sluice, your elevation (higher elevation means less pumping power in the engine), and to make sure your pumps water intake is as short as possible and unobstructed. Also the pressure of the pump is important as well, the more you have the less gpm you need up to the cut off points. Keep in mind that power jets require less gpm and suction nozzles require more. Several of the above dredges are running with those size or similar size pumps (but that doesn't leave a lot of wiggle room for improvement which is bad!). I believe you need at least 35gpm to make a 1 inch dredge work, at least 52 gpm to make a 1 1/2 inch dredge work, 75+gpm for a 2 inch and 160+ for a 3 inch.
