Good call on the Perfect Pass. I'm assuming you will take a test ride and test-out all the helm systems - pumps, lights, wake-tab, etc.
When I bought my 2007 the rear ballast bags would fill, but would not empty. I knew the solution was to replace the Rule drain pumps on the back of the bags. I used that to negotiate with the seller. The seller knew is was broken, did not know the cost to fix and did not want to mess around fixing it, but wanted the boat gone. I knew if I bought the boat the first thing I was replacing was the ballast bags and switching to reversible pumps. So it was all getting ripped out for new/modern parts.
There is a lot of help on here and on the Moomba Forum. SC boats systems are similar.
