View Full Version : Re-power Props

03-30-2012, 09:49 PM
Sorry to be this stupid, but I am replacing my 350's with 383's in my 2000 ZX 28, I was running 5000 rpm with 26 pitch Mirage 3 blade OEM stainless, I want to go to 4 blades and need 5200 rpm. Any ideas?
Thank you for your help :confused:

Try your mirage26s first. Might be good.

More info, what power?

I had stock 350 MPI's 300 hp, 3 blade 26 pitch Mirage 5000 rpm, new engines are Mercury Marine 383's 350hp, I need 5200 rpm, plus I think 4 blades will get it on plane better, the 3 blades cavatated bad. I have been told to try 24 pitch labbed 4 blades, does that sound right to get the rpm's up?

I've run the bravo 1 spinning outward and that was a scary ride. Too much stern lift. Try the 25 Rev 4's or turbo props 24's. What is your torque off those motors? You may want to spin them in too to see what is best for your boat. The scorpion boats spin inward
