That must be one special Mojo you got.
FWIW, I think adding a dedicated pump to the IBS is overkill, especially if you plan to run the 1,100's (or more) in the rear. I can't imagine when you would want to run bow weight without the center also filled and those combined (IBS @ 650 & center @ 450) will take the same time to fill as the 1,100 so you won't gain any overall efficiency. The only scenario I see where you would want it seperate would be if you had newbies/younger riders and wanted to only go 1/2 way all around and wanted some bow weight to lengthen a surf wave.
Someone flipped my "Ass" Switch years ago and I haven't been able to turn it off since.
Hey im just keeping this thread moving one "ASS" at a time LOL
How are you going to get the IBS to empty if you have it piggy backed off the hard tank? Whichever leg of the ibs you don't have he drain/fill hose connected to isn't going to drain.
Wowzers. I never thought in a million years that pump would be able to lift the excess water up and around the front of the boat to get it to whichever side the fill/drain line is on, from alllllll the way in he back of the boat. That's impressive.
