Ok guys I have a TRS drive with a 21pitch Quicksilver Mirage 3 blade prop on my boat. I heard the Bravo 1 props fit TRS drives..is this true? Also is there anything I need to look out for when changing pitch. I need to go up atleast 2 pitchs on a 3 blade or possible only 1 pitch up on a 4 blade prop since my 330hp 454 is spinning to 5,500 rpm's which is way to much. While I have you guys here what is the pro's and con's of a 3blade and 4 blade prop.

I would try a 24P bravo one prop to get you back down to the 4600RPM range where i think your 330 need to be. Or maybe a 25P mirage.

I should have posted that the 330hp 454 does have lighting headers, and performer intake. I know its not a big gain in HP and I know this motor has cast rotating assembly but does this motor only need to turn at 4600rpm's?

I believe the 330s had real mild cams. So spinning it too fast might not do much for you without a cam upgrade.

So does a bravo 1 prop fit a TRS drive?

Yes, I have one on my TRS. I lost about 1.5 MPH on top end compared to my Mirage, however my cruise picked up 1.5-2MPH along with several other benefits.

Thank you for the reply. I was suppost to hook up with a local that has several props for me to try out this weekend but I ended up getting sick and will not be boating this weekend. Weather is so nice here today in NJ and iam stuck inside the house. Hope everyone is injoying there weekend!

What kinda speeds are you seeing with your set up ??

I dont have a GPS speedo but iam seeing about 55mph with just me in the boat. Its a stock 330hp 454 with aftermarket intake manifold, and lighting headers. Now iam sure the speedo is off and would love to put a GPS speedo in the boat but that will have to wait.

you didn't say what hull...

but I agree with a 25 Mirage or Mirage +
