View Full Version : How to improve wake on Outback V with Gravity 3

I'd like to improve the wake for surfing on my '07 OBV w/ Gravity 3 and the upgraded prop.

Conditions:
1. Bags must fit in lockers. I can't have anything on the seats
2. Must integrate with the factory fill/drain system

My early research suggests the Fly High Fat Sacs for the rear lockers might be my best bet. Are they designed to replace the stock gravity 3 bags. Is the install plug n' play and pretty easy for a home install?

Any other suggestions?

Thanks !

750lb fat sacs in the rear - just switch out with stock 400's (plug and play).

That's pretty much what you can do without modifying your plumbing. You could do the integrated bow sac and piggyback the plumbing from your center sac (search the threads, someone with an 07 OBV did this I believe).

Thanks for the quicky reply !!!!

Can you, or anyone else, comment on the performance difference? I reckon anything that adds ballast will help.

I find running the 750, center 400, 400 in the bow on the surf side, and 400 on the floor in the rear corner, with just a driver and no other passengers is a really good wake. Wakeplat is usually 1/2 to 3/4 down which I find cleans the wake and lengthens it. Wakeplat all the way up makes it too washy.

you place the bow bag on a seat, or do you store it in a locker.

I need to find that thread detailing how to tie a bow bag into the center bag. That sounds intriguing.

In regards to fittings, I found one thread stating that I'll need 2xw736 fittings to make this work but haven't found that recommendation elsewhere. I'm going to check with Fat Sac. But what are your experiences? Are these needed or can I use the stock Gravity 3 fittings?

You can use the fittings from the stock bags, with two assumptions 1. that you don't want to use the stock bags for addtional weight, and 2. you can get the fittings out of the stock bags (they are cemented in). I got them out of my stock bags but it was a bugger. Then I used the plugs that came with the 750 and the Tsunami adapter plug on the stock 400's.

i think he does it manually with the tsunami pump.

Page 8 of this thread may help, Dan did a great job with adding the IBS
