Wow that looks great and I'm sure it works well, after what you've been through Brad!! I've probably spent 5k on stupid ballast projects, that's one reason I bought an SX, figured I'd be good with a factory system, NOT!!
My valves seem to work well in both directions, sometimes one sticks and won't drain, break out the surfboard!
Incidentally, I somehow managed to lose the four button cover plate for the ballast system. If anyone has one, I would pay handsomely.... Or I'll have my kid make me one with his 3d printer:)
The one thing that bothers me in the back of my head about wakesurfing is if the engine oil pump pickup works properly at a 45 deg angle. Cars are designed to go up and down hills, not on the sides of them:) But, I guess if enough guys have done it for long enough without issues, than its probably OK. Did I miss any "I put a rod thru the block of my Epic wakesurfing!!" posts in the last coupla years? LOL!
Nice job on the ballast control panel Brad, I will have to check those guys out!
