this system put out about 6.6 gpm or would take about 7.5 minutes to fill a 400lb bag up, or about 15 minutes to fill a 750lb bag.

then there is another 400 lb bag waiting to be filled so what is that like a half hour to fill everything up.

I just dont have the patience for this

next up using the factory pump with 1" hose and no valves

my garden hose could not keep up with it so i had to fill up a big bag and use that as my lake. this was running at about 19.3 gpm or would take just under 3 minutes to fill a 400lb bag up. and figure it would take just under 5 minutes to fill a 750lb bag.

next up -using 2 800 gph tsunami pups tee'ing off a single intake--this is using all 3/4" hose.

Edit: this is putting out about 15gpm for both filling into the same bag--figure each pump at about 7.5gpm

final test

this is 2 800gph tsunamis fill into one 1" hose, this was running about 12.5 gpm or would take about 3.3 minutes to fill the 400lb bag.

factory pump inplace and seeing how a new intake with 2 pumps fit on the drivers side of the vdrive

seeing how the other pumps will fit on the other side of the v drive

sticking the thru hull in to see how it fits

much easier to stick in from inside the boat for this trial fit--this is what the under side of the thru hull looks like

just have to put the nut on and let it sit for a couple weeks and let the sealant dry

how this is all working,

The original factory rule pump is filling my surf bag 750 lb.

2 of the tsunami pumps will be filling the front locker bag and the bag under the passenger seat where the cooler used to be.

the other 2 tsunami pumps that are going into a single hose will also be used for filling the surf bag thru the vent port-these are on a seperate switch and the hose will have a quick disconnect if the bag needs burbing.

hope it all works.

I am surprised to see that the two pumps going into 1" hose went faster than the two 3/4" hoses. I would have assumed that putting two outputs into one would have created some backpressure or turbulence to make it sub-optimal. Say, did you think to do the 2nd-last experiment with two 1" hoses instead of 3/4"?

Ian you were correct about the flow-I made a edit to it. I was just using all the hose that I had-didnt want to go out and buy more.

I may do away with the 2 pumps into the one hose, but since i had them figured i would give it a try-once i can do a actuall lake test i may give a try with just one pump and one hose-it will be very easy to try

What intakes are you using thru the hull and are they 3/4" or 1" inside diameter? Is the factory intake 1" inside diameter? Reason I ask is that you mentioned factory pump with 1" diameter hose...wasn't sure if you were referring to inside or outside diameter.


Using all 3/4 " inside diameter thru hulls-much easier for the pumps to screw into it that way. Using 1" would require adapters for all the pump intakes.

The factory pump uses a 3/4" inside thru hull and then the output hose is 1" inside diameter. -strange, but again i am just reusing as much as possible and try and shorten the fill time.
