Thanks again for the reply. I spoke to Spencer at Wakemakers and we agreed 2 reversible pumps will be the way to go. He suggested just keeping the system intact for the current ski locker and add 750 for rear, 600 IBS running off 2 new pumps. I have two 450 fly high sacks and he suggested using one port side seat if no people in boat. He gave me the suggested 'kits' including the install components. I was wondering if anyone had any suggestions on links to good threads I can access to see anyone that has had some previous experience with similar project for 07 OBV or similar. Wondering about best place to mount pumps, switches, see pics etc... I'm sure there are some threads but having some issues searching them out. Thanks.
