Mistress with 600's propping?? speeds?
I am about to put in 600hp engines in my Mistress, dyno proven 600.... what would I start at with propping on TRS? the doner boat has Hydromotive Q4 27, I know the Mistress wont spin them, I was thinking in my hull a 3 blade 25Mirage plus? or smaller 4 blade for sure...
I assume I am looking at 72-74 mph best, the doner boat ran 78 with TRS... its a 34 ScarabIII
just wanna see where I start

My Mistress is out for interior work, I hurt one engine last year and it is ready to go back in. They are Hawk 540s and I think they are about 600, it will run 73-74 with #3 drives

I agree with you and Harvey. A Mirage Plus (25) is a great starting prop. The Mirage PLus has plenty of blade area so nice out of the hole and nice cruise. Might suffer a little on the top but not much. The Hydo Q4 bites hard on the top end and is tough on drives with a heavy boat like yours.

Yea, I alrready figured most likely going to 25 Mirage plus, I have a nice set of 24's I will use for a base, I don't even know if I will run the boat with the 27 Hydros, no way in my mind do I think it will spin them in my hull...
I am happy expecting 72-74 out of it, I think it should be around that... so that's sweet speed gain!!
