Nope...

Mercury only produced 27P, 29P and 31P props. No doubt there were some test props in various configurations that were made but never released to the public. I do know of at least one propshop that modified a set of 31P props into 32P.

Most people with high HP Blackhawk setups regear the drive to 1:36 and spin the heck out of thier props..

Gero has info for a guy down in Oklahoma that can do anything you want for BH stuff, but it will cost. Something like $2k a pair. He does have several test sets that you can try. I can get you the info if you want it, Shane.

You get much over 450HP spinning through a BH drive, which would necessitate bigger pitch props, get ready to start customizing a lot more than props.

I would go the Woodsy route first.

It is actually Shea but I have been called many worse things before:)

the question is actually coming a little early as i am having a new motor installed in the boat for the end of the week approx. 500HP and was pondering the thought that I could probably go to larger props when this is done after some sea trials

anyways we'll see how it works and decide from there

I am checking into the gear ratio of the drive tonight

thanks for the info

Slow, but in the lead :D :D

Geez, this forum needs a good moderator, anybody want to volunteer?: :smash: :shocking: :hyper:

Shea or Doc, not sure who is throwing a rooster my way, but I welcome the opportunity to see it happen.

Now, where the heck were we on this completely de-railed thread?

Please keep us posted on how it performs.
I have several new Blackhawk gear sets and drives in various ratios if you need to change.
