So we'll sneak down, yank the 600 out and drop in a 525 5450 rpm engine, set the weight at 5000 and the drive at 1/2" below, put on a 31" pitch & 15 5/8" dia prop, and see what we get. Then, in the morning, we'll have it back the old way....
Should be no problem, no one will ever know.......:sifone:
