Hydromotive props have worked out great on my two Fountains. 1999 32 Fever with 502's and 2004 38 Lighting with 525's. My 32 came with four blade Hydros...I can't remember the pitch for sure but believe 27's. Also the boat came with Fountain steering...yes Fountain made it. The steering looked like Latham but the cylinders were a brushed finish not polished like Latham. My 38 came with four blade Merc Bravo 32P props but runs much better with 30 Pitch P5X Hydros.
