i've never tried it on sterndrive but it should work<br />what it does is creates exhaust bubbles on the back side of blades allowing prop to turn freer<br />note: must be through hub exaust<br />too large of a hole will just make prop ventilate and holes will have to be plugged
Yes, it works well on sterndrives too, just be careful of hole-size.....assuming you have the proper paperwork showing you where the holes are to be located, start at 1/8" and test.
Hi yes I have reviewed several post of the last couple of years. I have a buddy that has problems with a 27 ft Searay single engine. Has tryed several props and still has the hole shot problem. I just sugjested it to him and never thought of the I/O thing.<br />steve
