Best high speed prop for an HST?

[Boz]

I have a 14 1/4 by 29 SRX on my HST right now.
What is the prop of choice that will get me close to 100 mph w/ 270 + hp?

I asked that question awhile ago.

balzy's reply should answer your question.
I am sure that someone will have some other ideas though.

Don't know who worked it, but it works real nice. For top ending it's a 32 lab cleaver and I just picked up a 34. :eek: It seems a 27 or 29 srx works good too, but I did'nt have each one long enough to really get a good comparison.

Boz,

My HST ran well with a 29 SRX.

Are you close to 100 now? If so, send it to DAH Custom Prop shop. He known to work wonders on the SRX. He did a nice job on mine.

Mine ran 102 at 8200 on the gps
With one of Johns (DAH) 27 SRXs

What kind of power were you making?

Im not sure it was sort of thrown together as a experiment.
I would suspect somewhere around 240.

The combination was the following.

Tired 1992 Production shortblock
2.4 BP carbs .082 (134&6) .084 (2&5) jetting
4 petal cages with tdr reeds on a crossdrilled intake
32cc heads of my design
HP. divider plate (no bump)
41941 tuner (2.4 200) mounted on a -1" milled adapter plate
Timed at 25 degrees
mounted on a fabed by me 15" exhaust housing using a very nice 2 hole cle

the 27 was the biggest i had at the time ( Im sure it would have went faster with a 29 with less rpms)

The boat also had 12" of additional setback an ran with negative trim.


It is now over a year later and almost water ready
with much bottom work
Widened lifting rails & sponson bottoms (same width front to back) I also moved the dash 8" aft and instslled wire rope steering

as for the motor
2.5 efi around 300 hp
sportmaster ect.

I also have seen a lot of DAH SRXs @http://www.bassboatcentral.com/props4sale1.htm
