I have a 1976 Cig awesome running 420hp 454's with SMI exhaust,the original BW trans & trs drives.The drives do have nose cones on them.The props are marked 21p Mirage plus. The previous owner said that he had the props "shaved"? It will run around 58mph top end at about 5300 rpm. It seems to me that it should go faster on top,it does accelerate pretty quickly. Can anyone tell me which props they have used or would suggest? Its 35' like the mistress but with the raised deck no idea on weight.

I think you should try a set of props to lower the rpm and see what happens. Since your props have been worked it may be worth a try to test a set of 21 Mirage plus or 23 Mirage plus. It may get your WOT rpm around 4900-5000. Then you can see what speed you get. If the speed increases the motors have more power at that rpm, if the speed decreases then the motors make less power. Its like a dyno on the water.

If you have dyno runs on the motors then that would make it very easy to know what rpm the motors should run at.

Thanks I will try that ,have very few hrs on the boat since I've had it. I do have a brand new (in 1976)set of Mirage 21's that came when the boat was new & are still bolted up inside the bow. I will try them first & check rpm the motors feel like they could pull more.
