Tightening three or four bolts on this Walter puller (waltergear.com) compresses the two plates together—one between the strut and the propeller and the other centered on the end of the propeller shaft. Two sizes cover up to 3-inch shafts. This works well on three- or four-bladed props. Once props have more than four blades, though, the leading edge of one blade typically overlaps the trailing edge of its neighbor, so there is not space for the bolts to pass between blades.
This Memorial Day, remember those who were lost serving our country on the high seas in the U.S. Navy aboard PT Boats. Recently we were invited out for a ride on the only operational combat-veteran PT Boat, PT 305 in New Orleans.
