Mod Edit:
Three prop sizes for different power on this craft.1: 17x17 for the Volvo penta small block. wot should be 4600rpms. I think 12 is max persons. there is a brochure with specs somewhere on this site.
2: 19x19 4-blades with some cup was where the magic started to happen for me with carb'd Vortec 350's. Was slightly over-propped, but pretty close.
3: I have a 1988 290 TM with 350 Crusaders that are 260 HP.
My props that came with the boat are 19 x 21 3-blades
I run the engines at about 2900 RPM for cruising, top end is about 4,200 RPM on mine
