Did you by this boat from the new Tige dealer in UT, or from Taylor's. The new dealer may be new to tow boats and going through some growing pains. If bought as a left over from the old dealer, they have no real incentive to fix, IMO.
Ballast: Some of the 07 did have a vapor lock problem in the pump manifold. Temporary fix - try filling front sac first, also move a few peeps to the front, this will get the bow down and allow the trapped air to burp back out the transom intake. Also drive in revers with pumps on, this will force the air out of the manifold through the pumps. Permanent fix - reposition the manifold so it is lower then the intake, this will allow the air to purge when boat is launched.
Next, can you confirm whether this boat has the round Perfect Pass control(not available from factory on 07's so may be dealer installed) or the factory Speed-Set that uses the LCD display on the main gauges.
Congrats on the new boat. If the dealer continues to be a prob, call Tige @ 1-325-676-8570, and they can help you get ahold of your area Rep.
