Re: Maximus on 382
 

Magicfloat,
I can turn stock 28 bravo's on my 382 w/o boxes and 620 HP to 5500 rpm.
Have you seen good results with maximus props on a non boxed 382?

Re: Maximus on 382
 

Yes,try a set of 26's,don't lab them. Our latest results show that the only reason to lab props is to get more rpm if you need it. On heavy boats like Formulas it seems labbing just causes more slippage. But your best bet is to listen to an expert like Brett or Julie. Props are not science,they are art,an artist is needed for best results.

Re: Maximus on 382
 

Probrably should have clarified my last post somewhat about lab props. Lately our results on Formulas have favored stock props,but we don't have the testing facilities that the larger prop shops have. For those of you that are really serious,put your trust in folks like Throttle up or BBlades. They have much more knowledge than I do. They are the artists.

Magicfloat,
Thanks for your input. From all the testing I have done with the 382, I am beginning to believe that a lower pitch non-labbed prop is the best all around vs a labbed higher pitch.

Re: Maximus on 382
 

Well, I got a chance to run the boat today with the new props.
I still have some dialing to do but the preliminary report is:
99 382 with 1.5 Bravo Performance drives on Stelings boxes 500EFI with head work, bumped up cams and ECU mods ? 550ish HP (no dyno). Light load, 1/2 tank fuel
Lake Michigan, Calm
Water Temp 47
Air Temp 71
14 7/8 x 28 pitch labbed Bravo 1s 3500 RPM 45 mph
15 1/4 x 28 pitch labbed Maximus 3500 RPM 54 mph :D
Top Speed GPS:
Bravos 76 mph @ 5500 rpm
Maximus 76.8 mph @ 5000 rpm :woohoo:

I'm in debate over whether to sell these and drop to 27 pitch, but I really like the cruise speed and in the real world, WOT is a rare occurrence :drink:

Re: Maximus on 382
 

I just ran the slip numbers
Bravo 1 3500 rpm = 45 mph = 27% slip
Maximus 3500 rpm = 54 mph = 13%
Bravo 1 5500 rpm = 77 mph = 21%
Maximus 5000 rpm = 77 mph = 13%

In this application looks like the maximus is the clear winner -

I have a non step 382 w/ sc 650's I'll check my slip #'s with Bravo 1 28's when the motors go back in

Re: Maximus on 382
 

Sea-crit - about your slip numbers - they are so bad maybe you really have # 26 props and not # 28's

Re: Maximus on 382
 

They really are 28 x 14.75.. The previous owner must have had them cut down to get his revs up before the engine mod's.
I would imagine that a set of 28 x 15.25 bravos would work much better, which I may do as a second set to compliment the Maximus set. :drink:

Re: Maximus on 382
 

Thats fast! :drink:
