Pantera 28 F1 Prop Recommendation
I am just finishing rigging my 2003 28 Pantera with the F1 layout. It has a single 530 HP @ 5,300 RPM Dyno'd 502 with the notch transom Bravo 1 LWP and without the full cabin (recreational stuff) and a minimized liner and custom layup. This boat runs about 1,000 pounds less than a pleasure single version from what I have heard.
I will be adding a little weight back in compared to a true F1 with some minimal cabin cushions/carpet and a aluminim swim platform.
Previously I'm told the boat ran 93-94 with a 750 HP 540 blower motor and a 32 labbed B1 four blade.
I did a historical search in Prop Talk but did not find any other similar Pantera situations. What prop(s) should I be trying as I get this out for testing this spring? I have a Bravo 1 4 blade 26 and a Hydromotive 25 4 blade to start based on some factory recommendations. I assume 5,300 should be my target max RPM?
Thanks! Mike

Reason: corrected pitches on props

You have 2 excelent props to try. This will give you the baseline to determine if altering one of those props is the best decision or whether going to a different brand is a good option.

Thanks! should my max RPM target be the peak HP of 5,300 RPM running light? I assume that is best because 5,200 is only a few HP less per the dyno sheets and that would still be a good RPM for a heavier load on some days while easier on the engine. What rev limiter chip should I use as well ?? 5,600? I'm new to propping for max performance.
Thanks

When I got my boat, it had a 26p bravo on it, with a breathed on 525SC. I was getting around 5,200 rpms with that prop. My boat is probably 800# heavier than yours (if I recall what Jo told me correctly) so you'll get more rpm out of a similar prop.

I would bet 28 Bravo 1 prop will be real close.

Mike,
If your HP peaks at 5300 rpm, consider using a rev lim chip at 5400 rpm. No sense spinning up there if there is nothing to gain. Carder

OK great, thanks everyone .....
Griff, that would be awesome but do you really think I can spin that tall of a prop 5,300 on a 28 single 530HP ?? seems tall ..... why do you think a 28 B1 ?
