353 props and speed?
Just curious what speeds and props you are running with your 353?
I've got 500 efi's and 30p bravo 1's. Best I've seen was 77.9 with just ove 1/2 tank of fuel. Approx 5100 rpm. I guess I expected just a little more out of her.

That's right within a couple of mph. You can tweak the props for another 1 or 2 maybe, but you are real close. I personally wouldn't spent the $400- $800 to pick up the last couple of rpm's/ mph.

I have a pair of 525's and I'm running 5 blade 28's Mercury Maximus. Top speed so far is about 76-77 on GPS

You should be able to run 79-81. Need to loose the difuser rings, will give you a couple. Do you have ITS?

The 353 hull really gains BIG MPH from more power
Easy over 90 with twin 600 -
almost 100 with twin 700
Props 32 Maximus lab finished
600 - 1,50 gears
700 - 1,35 gears
compared to 496 HO `s 73-75 MPH
and 525`s 76 - 80 MPH
The 600`s are the very best package
You only gain about 5 MPH from 425-525
13 MPH from 525 - 600
another 6 MPH from 600- 700 (not available from factory)
Would be interesting to see speed numbers of the new 8.2 HO `S

No ITS.....B Blades did the props, thanks for your suggestion last summer, they did a nice job...no diffuser rings. Still struggling to get her dialed in any faster.

I'm struggling to believe the 496 HO's will push a 353 to 73-75 MPH. The 525's are a total 200 more horses and only producing a few more MPH for most 353 owners.
