2015 OBV bow bag

[Richied718]

I have a stock gravity III ballast system. Recently just bought a 750lb bow bag does anyone have instructions on how to pipe it in on center bag. I DO NOT want to use an external pump anymore!
The new bag is a Sumo.

I piggy backed my bow bag off the center tank. Super easy to do. I'm on the road for work but I'll try to get you more info over the coming days. Wakemakers can also talk you through it on the phone.

I did the same as Karl, here's my setup - worst part was pulling the center bag out to get the 90* fitting in and drilling the 1 1/4" hole in the floor of the front locker (not hard but nerve racking!)

I left a 'service loop' in the fill hose to ease the alignment of the tail of the bag and fitting through the floor:

Is there any way of doing this with out drilling ? How much should it cost?

I don't really recall how I routed the hose but I didn't need to do any drilling in my 2013. Maybe there is some difference in the model years that the 2008 needs to have a hole drilled but the later models don't??

The only cost I had was a few clamps, a new section of hose and the IBS sack itself.

I also did not have to drill any holes in my 2014 either.

I did. The only access to below was either under the hump in front of the driver's feet or in the cubby where the battery cables, etc. come up. I drilled a hole half way up the bow so I could run from the center bag to the top of the IBS bag without kinking.
