Thanks for the information. I have another question. I read an article just this morning while doing a search for the torque-shift prop,<br /> http://www.stingrayboats.com/products/reviews/tb3_99.html <br /><br />They tried the 144-126 on a stingray 3.0L sterndrive and found it ventilated and slowed 0-30 times. They then tried a 144-132 and it performed better. What are your thoughts, is this due to the boat hull-motor setup or something else.<br /><br />Thanks again
