Congrats on the boat!
Pumps.... Most likely the impellers and design.
Ballast..... Call Wake Makers. One stop shopping, great customer service and they know their products. They'll set you up with what you'll need and it'll actually work.
Perfect Pass.... I upgraded to StarGazer this spring. Love it. Be aware though that if you want to run RPM mode on slalom you will still have to calibrate for speed vrs. RPM. Operation is about the same with the menus for setting up favorites and speeds.
