There are two guys here on the forum that have the '06 24SSV and '07 22SSV and both have done upgrades to their ballast. I'm not the one that will have a good answer on the fill time or pump not priming. They will have better answers than I would.
As for the motor, I have the 345 horse in my 242 with the Acme 1235 14.5 x 14.25 and that was the same concern I had before purchase. I'm more than impressed with the motor. I load it with over 3k ballast and anywhere from 6-8-10 people onboard and no issue whatsoever. You do have to balance the weight. If you put everyone in back, it will struggle to plane, but overall it gets out of the hole quick and does well on gas. I would check your prop size and if it needs an upgrade, that will be money well spent.
For comparison, the '12 Sunsport 242 weighs about 550 pounds more than the '05 24SSV from the factory at 4,500 lbs. vs 3,950 lbs. respectively.
The Indmar 340 hp was the optional engine for that year over the standard 325 hp across the 8 models that Supra produced. That engine offered new ETX one-piece tuned-port exhaust manifolds that gave it a 5% increase in both torque and horses with high-flow heads and a high-lift roller cam. You should be fine if the engine has been well maintained. The Chevy 350 is a great motor. Performance wise, it will get the job done.
