good question, i do not know the ratios

500 efi is rated at 470 at prop. 525 is 525 at prop and i hear they are often actually putting out more. I was curious how they run with 525's also but had assumed they would run close to as fast as the 575's which are rated at 550/prop. Any one here own or have run a standard poker edition with the notch and 525's? I am seriously considering this setup.

it really comes down the the ratio and prop selection. the majority of boats left the factory with 1.36 ratio and 34 bravo 1 props. The norm for those boats was in th 110-112 range. Regardless of the hp of the motors, if they turn the same RPM and run the same prop and ratio, the speeds will be pretty much the same. i am not saying that it wasn't possible to run faster, I am just giving the numbers that most of the boats ran. Zipp Express was the exception running 116, but it didn't do that on a regular basis. that number took 36" props and almost no fuel.

If it helps...

my set up is a 2003 36' PR, 650's, 1.36 ratio, 34P Bravo props, 200 hours on the motors. notched transom, ran a best of 118 gps. Motors are getting refreshed this winter and we'll try for 120 next summer.

are you running the MDG 650's? what rpm are you seeing?

obrien is right,36 pleasure with 500s and bravos would just touch 110 on a calm day. With the 750s in it now it will run low 120s.

I have a 2001 Spectre 36 Poker Run with basically stock 500EFI. The previous owner claims to have adjusted the REV limiter, to allow greater speeds, however I am not 100% sure. My boat has 1.5 ratios, and with Bravo One 34's I am running over 6000 RPM's, and I have never heard the rev limiter. I am at about 97 mph with the Bravo 1's 34p, @ 6000 RPM, but not yet wide open (I don't want to twist it that hard). With Hydromotives 33c P5 x's, I am at about 5700 RPM and 103 mph at WOT. Could I run a Bravo 36p and keep the same top speed (maybe better), but yet bring my RPM's down? The 500EFI's say 5200 RPM max. Is it safe to pull more? Any prop better at controling the mid-range porpoise? Can I pull a Bravo One 36p and still get on plane ok? I really love the Hydromotive props as they have much less vibration, and plane without any cavitation, but for all around use I would prefer to run the cheaper Bravo Ones. Any advice would be appreciated!

I'd think at 6,000 rpm's your already (twisting it hard) for a 500efi.

I think you are correct.....6000RPM is too much. Previous owner told me "no problem", but he was selling, and wanted to give the 34 Bravo 1 props away with the boat, rather than his labbed finished 36 P props, that he claimed "were not his". Does anybody have one of these boats with the 1.5 ratio and 500 EFI. I would like a little info before I start ordering props. Is it possible to pull a 34 pitch Hydromotive PX 5 blade and still come on plane easily? Or would the 36 P Bravo One be the best all around choice?

All the 36 spectres we set up would run 34 pitch bravo 1 1.36 ratio,the 34 bravo seamed to handle the best and settle the boat in easier,with the mdg 650 would we see around 120 at 6000rpm.tons of throttle response,some i ran labbed some stock,i would set your boat up with 1.35 ratio,34 pitch bravo,should run 110 on a good day at around 5300-5400rpm,that is if your motors are still in good shape and not too tired
