I had a 2001 28' with a 496 which is close enough to your power. Not sure if you have the step or not.

In my case...it was a compete and total waste of time and money. The gains are so minimal that it's not worth the effort. As a matter of fact...I'll never deal with labbing on any furture boats!! I actually lost performance in some situations. I went with a stock 24p Bravo, at 24 Bravo re-pitced to a 25 and labbed, a labbed 26 and they did nothing but cost me money, lost boating time, and performance. The best performance in the top speed was the stock 24, cruising was the lab 26, but I couldn't spin it past 4800.

Maybe somebody else had better results, but from my perspective with this hull and power, save your money, stick with your stock 24 and put your money elsewhere.

Indy's probably correct on the 496 engine, however, as you go up in power (500EFi or 525EFi)the labbed props make a difference. I have had two 28's one with a 540 Bulldog and one with the 525 EFi in both applications the labbed prop allowed me to run a taller pitch and still accomplish max rpm's.

Gary,
How did you come out on props for your Flame? Did you ever get a 5 blade prop setup to work?

Thanks Bill

Bill,
the stock 24 is probably a good choice for your non stepped hull with much lower X dimension.
I have tried many, many different props for my step hulled Heat and for any Heat 2001 or newer with decent hp, there is only one prop. This would be the new P5-X with a touch of added cup.
See my reply in this thread for further explanation.

If Nordic does not make this standard issue they're missing the boat

rv, the five blades were awesome in every area but top end. I got to my rpm range with the 28 labbed fives but fell 3 to 4 MPH short on top end. Running 32 fours hitting limiters. Want to re-pitch the 32's to 33's .

Gary,
Thanks for the reply, sounds like they were good but 3-4 on top end is a big difference. Good luck with the 4 blade one.

Did you notice how much speed increase at cruise (3500rpm) with the 5 blade?

My last attempt with our labbed 30's from Houston Propeller is much better than the first lab attempt but I don't think it is quit right yet. Seems like I lost 1-2 on the top end from stock setup. However, the chine walk at max trim is gone, the prop holds the water much better, can trim higher and in rough water it doesn't break loose as easy on waves. Still need to do some more testing before going back to Houston Propeller.

Im Running a 23p mirage plus right now, blows out in the turns too easy. and I can change the top end speed by just moving weight from the cabin to the stern and pick up 3 mph like the cooler and gear. I thinking im getting to much stern lift. also notice I can run faster with full tanks which are mounted in the stern area. my top rpm 4800 hot humid ,5000 cool clear day speed 58-62 gps with 5200-5400# including fuel,gear, 2 people. I thinking the 22-24 pitch area was where Im going to end up.
Thanks Bill

Man, and I thought those characteristics were only on the stepped hull version
The Heat is EXTREMELY sensitive to bow weight. I have always said I can run faster with 3/4 tanks and a couple people in the back seat ;o))))))
Put some gear in the nose and run on flat water and it's a pig!!

RV had a 98 I believe with a 454MAG and a 22 or 24 pitch. He may be able to chime in on your application.
