of the boat. In my opinion you will loose some top end. You may or may not correct the slight draging your port tab issue. but you will more than make up the draging of a small tab by wetting alot more of the surface of your boat , which would create a whole lot more drag than the tab. These conventional v 24's will run fastest with the bow up. If It was a step-bottom boat I would agree with a little stern lift. 8 or so % prop slip is great, So my opinion on a 4 blade is that you may pick up a little mid-range & drivability it will probably come at the cost of a mph or two on top end. Forgive me if I missed this but does the boat porpoise when you are in the boat by your self , or when it is loaded down ect.... Can you make it quit by dropping the trim a touch ?

There is no way I could cruise with the tabs all the way up, it would porpoise like crazy. Even at WFO in smooth water it porpoises a little unless you drag some tab. With some chop it doesn't. But in the boat snot you definitely have to drag some tab(I've found about nuetral seems to work the best) to keep the nose from skying off of boat wakes coming in from the side.
I really don't care about the port tab being lower to stay level. I am more concerned with top speed/handling in the boat snot. My logic was if the bow didn't want to launch(less bow lift) off of side boat wakes I could run less tab and MAYBE run faster. But, my thinking could be off.

Re: Props for a Pantera 24
My opinion is if you are wanting it to run better in rough water & have the best handling you might want to go with
a 4-blade bravo. But I believe it is going to cost that last couple of mph on top end in calm water. With the right
labbed bravo prop you may possibly keep your top end where it is while still gaining the better sloppy water caracteristics of a 4 blade. I believe it is going to be hard to get a better nasty water prop & gain top end at the same time. I am shure you will get many opinions on this subject but I hope this helps some. Also I am not shure what a stock 415 hp 502 should
turn RPM wise ?

And that very well may be the case. I like the way the boat runs now but I don't like "not knowing" if I am completely dialed in. That's why I figured I'd start this thread to see what others have found. Stock 502 MPI should run 4800-5000 rpm and I THINK the limiter is 5150. I like to run them close to 5000.I was also told that the 4 blade Bravo 1 did not work well on the 24 and the Hydro was much better, but I can't remember where I heard/read it.

Re: Props for a Pantera 24
The Bravo prop is no good for that boat, it feels like you're going to roll over.
I don't remember if a readjusted the tab indicator after I installed the new rubber boots on the tab indicators. You may not be dropping as much tab as you think.
Have you pulled the boat on the trailer with the tab set at the same point as you ran it? I'd do that first.

My point was the SE model carries a little more weight fore.
