I had a BTX/Bossman Tortuga with a Suzuki 60. Boat ran very quick ( 36 - 38 mph ) with the stock stainless prop in a 15 pitch. I believe Solas makes the props Suzuki uses as stock. I did not get the shallow water performance that I needed so I switched to power tech SWB 4 blade 13 pitch & had a fair amount of cup put in it. Boat ran about 34 but had excellent grip & would jump & run with the jack plate at the top.
