Wait for someone else to confirm but I think 750 is all that's going to fit. I know it is that way on the 05 21v.

I have a 2009 21V, and I upgraded from the 400's to 750s. There are 1100's that apparently are just a bit too big, unless you get them custom. The 750's do leave room on top, so you could get more back there if you got a custom bag. I've read from others they got the 1100's in, but also had one person tell me (I posted on this before, check old threads) that they cracked the engine side of the compartment.

Wakemakers told me the cost of a custom bag was I think over $1000, so I'm living with the 750's, though I think I've not got enough weight yet for surfing, I'm struggling with my wave.

Can you explain how you installed the 400's up front? That sounds very interesting. Any pictures? I've been putting one 400 up front on port side and filling with a separate pump - would LOVE to get them filled via stock pumps. Please share.

i cut the main line going to the front bag and installed a tee and a valve then hooked the bag back up.then ran a line off the tee to the front of the boat to another tee with a valve on each side then ran them in too the bags under each seat. the vents i ran in to the stock line. i think im close to 300 in each bag and with the valves i can fill the bags i want plus there are no bags on the seats.I have the part list if any one wants it it was a simple clean install i will post photos.

Please (!) do post both - I can't see how you could possibly get 400lb sacs under the seats if you've got the same boat I do but I'm super interested in seeing how you did all this.

The 1100's fit . Do not waste your money on the 750's. You do however have to beef up your engine wall support at the bottom of the wall. A simple angle bracket screwed into the floor in the middle of the wall will do. Then you can use your 450's under the seats as mentioned above, but you won't be able to fill them all the way. You will have to cork your air vent when surfing or the 1100 will partly drain out the vent line. I can surf all day with the stock 450 ballast , there is just more wave to play with with the 1100 lbs.
