Just bought a 2014 z 1 and owner didn’t disclose some issues so looking for some help. When I fill the port side rear ballast, the engine cavity fills with water. The rear bilge pump doesn’t keep up pumping water out and the front pump by the v drive doesn’t work, where can I find a few ballast to replace this one? We verified the sacs in the back don’t leak and no water when we fill the starboard side. Kids were so excited to get a surfboard and have t been able to surf yet due to problems with the new to us boat…
