Re: 30hp etec prop opinions

quote johnyrude200:

I hadn’t even thought of that, good point with planing vs top speed. I have my motor set with the ventilation plate about 1″ above the bottom of the boat. I’ve set most my motors up this way and it seems to give an extra 2-3 MPH once up on plane. You think this would help avoid the extra drag off a hydrofoil that you are talking about?

I also checked my prop – it is a 10.3 x 12. So switching over to a SST 14 or 15 pitch, I would think, will make a pretty noticeable difference in speed? I top out at 27-28MPH, going 31-33 would be a pretty big difference!

Its possible the height will be enough to overcome the drag issue. Is the hull at the transom flat, like most lumies? Do you have the possibility to raise the motor a bit more if needed? If both answers are yes, you have rested one of my two hates with fins. As for the prop, we still need to know the RPMs at full throttle with your 12" so we get it right.

If you have too many, AND not enough, you're a collector.
