Have you ever wondered what was going on at the back end of your boat? I stumbled across this video last night. It is interesting to see how much the pump actually moves around, along with the transom. I am sure a lot of the movement is being caused by the ride place. There has to be a tremendous amount of force being placed on the plate and pump, then into the suction housing, bottom of the hull, and transom.

It is also interesting to see the flow of water out of the nozzle as it is going thru its up and down motions. I am trying to figure out the forward motion of the boat/our boats at speed when the nozzle is in the full up position and a large portion of the flow is actually in the air.

I wonder if the nozzel o-ring was replaced after this video, along with the rudder?

Forward motion is pump inlet. You could set the Diverter straight up 90* and you’d still move forward. Great clip tho.

Im curious to your thoughts on this.  Then why even compress the water and spit it out a smaller nozzle?  wouldnt you just want a 7" nozzle to get the most volume of water through the inlet??
