Lot's of info coming in, interesting info. Here's a few answers to the questions. Yes WOT is 2500 NL WOT is hitting 2700 (rated on engine is 2650) I ran her in water 14-18 ft deep. I won't get anything deeper until I get out of the Trent Severn waterway later next week. The props seem to run pretty linear to old ones up to 1900 RPM, that's when they go sideways, I suspect based on comments earlier, this is due to the cupping not the pitch?
