Question about Fat Sac 750 in 2012 OBV

[Outback Skid]

Just ordered a fat sac 750 to put in rear locker for surfing. Do I need additional/special fittings for it to work with the boats existing pump? Don't want to spoil a trip to the lake with lack of equipment.

I have a '13 OBV and my switch was plug and play -- remove the old sac and swap in the new 750.

NOTE: You will have to take the fittings off the old sac and move them to the new which can be a hassle if they are glued in, but nothing new is needed. Wakemakers has a nice how-to video on its site on how to get those stubborn fittings out if they are glued.

If you have the newer reversible pumps you will need to extend the pump timers.

Thanks Guys. Can you buy fittings for the new sac so you don't have to swap out? My daughters are wakeboarders and will probably be moving the 750 in and out for surfing. Not sure I can make wake even on each side with a 750 on one side and 400 on the other. Maybe I should have purchased 2 750's.

Yes Wake Makers sells them new. Not very Exp.

The pumps are all timing based, so if you wanted to fill both sides to 400 lbs just shut off the pump for the 750 when the 400 starts venting or the pump shuts off. Probably won't be exact but close enough.

And you're probably going to wish you bought two 750s at some point, especially if you have any goofy surfers. :)

i got the tsunami pumps and adaptors and use the 400's for more weight also you need it!
