Maybe he'll teach us both after his nap. This was no factory low hp set up, it was from a real SS boat. It uses an 8 deg Casale with a 1 1/8" output shaft, an adaptive 6 bolt coupler (1 1/8" to 7/8"), drop through strut with a 7/8" bushing, and a 1" prop. Looks like it was a 1" shaft that was turned down to 7/8" right in front of the prop.
