Default Buying a new prop
At the moment I have a Merc High 5, 21P prop on my Z241, powered with the 7.4L MPI ( 320 HP ) with a Bravo 1, I have decided on a mirage Plus for my next prop as I would like something with top end performance. Not sure on the pitch yet, Is anybody out there with a similar power plant that can help with pitch selection ?

    WOT RPM was 5100 and climbing, I throttled back soon after for fear of engine damage. A quick look at the GPS showed 41MPH.

    A Mirage Plus 23P is probably best, or a 25P may even work. If you could barrow any 3-blade for a initial RPM measure it would help get a better starting point.
