I have a 86 Baja 320 Force, 400's with TRS, I run standard Mirage 23P now, I have seen a best of 65mph at 5000 on GPS, it definently needs more bow lift and I know Mirage Plus's are better for that, but is there a 4 blad that I could try to get more cruise and similar top end? I know top end will be most likely best with a 3 blade, but I also heard that some 4 blades may equal same top end while lifting bow and get more cruise, I average 44 mph at 3500 right now, I would love a better cruise since I spend alot of time there.
I do not have alot of other 320's to compare with as most have went to bravo, or have 32 Calibers with same hull but again, Bravo boats..
I tried drives spinning in and had pretty much same results but horrible driveability in rough water, I am on Lake Erie and like runnign in the rough stuff so I like drives spinning out, at least for now!
If the boat is a 65 mph boat I am fine with that just want to make sure I have best all around performance..

Just reread your post, thought you were running the 23p mirage PLUS props right now. Maybe a 21p might work better in the Revolution prop to keep your rpm where it is. I'd ask Brett from bblades. He also has a prop demo program.

OK, tried the Hydromotive 4 blades yesterday, 23 pitch, I was very surprised at results...
3500= 49 mph cruise
4600-4700 =62 mph
The lake was flat, I bet it would hit 64-65 with 3-4 footers as this boat runs best there, I do still have bottom paint on the boat that I hope to remove this winter since I finally found rack storage, I was always told it slows you done 1-2 mph, then yesterday had a friend tell me when he had to put it on his Formula he lost an honest 5 mph, boat drove great with the 4 blades, I really like them, I now wonder to get rpm up should I have these worked or go with a tad smaller pitch?
Again, I was amazed at results, I did not think it would break 57-58 with a 4 blade, I was wrong..

I think if I work these props it will be sweet, I was just out agin playing with some timing also and saw 63 in flatter water then yesterday, hopefully with some chop it will get better yet, I am on Erie and the lake is amazingly flat this weekend, normally it is tore up...
