Hi everyone!!!<br />i'm new to the forum here, and i was hoping for a little advice. what i'm setting up is a 17' Boston Whaler and a 1963 Merc 850. The engine came off of a lake boat in canada, no clue what size it was. I'm just trying to find a good starting point for prop pitch. the whaler is an older, surplus forest service rig. not sure of the model, it's one of the ones with the side steering station, i think.<br />thanks for any help

Hi, Spoon.<br /><br />I would start with a 17 pitch on that Whaler. Move up or down depending on WOT rpm.<br /><br />Good luck. :)
