Just picked this boat up started a thread in the classic offshore forum. Please read through that but here's some photos any info will be greatly appreciated.

Not sure what year your fountain is, but I have the very 1st Gentry twin turbo Fountain that Reggie built. All 5 boats that were built were called the Phase 5 turbos. They all came from the factory with the side vents double stacked for easy access to the outside turbos.

post up some pictures of yours, I could’ve gotten my hands on a fountain turbo a couple years ago but didn’t end of getting which I regret a lot I believe the one I was going to get was a 85 and was just the hull no motors or drives
