I read an article about drilling a small 1/4" hole at the leading edge of the blades through the hub. The idea was to allow exhaust gases to pass through the onto the blades allowing it to slip a bit off the line. <br /><br />I have a 1967 seaswirl w/120hp merc I/O, and what I can only guess to be the original prop which is in good-far condition.<br /><br />My question is does this modification realy help out with hole shot? It's one of those things that just seems to easy.
