The Boating Magazine test on an I/O Seafari showed running angle continued to drop up to about 25 mph. It's optimum mpg was at 19 mph, where the running angle was relatively high, but it evidently didn't have as much hull in the water at that point!

good to know, thats how I measured it too. when i took my video it was with the previous engine a merc 115 before it blew up. i'll give it a shot in the pond hopefully late this month with both the 15 pitch and 17 pitch.
