Cleaver props I would'nt reccomend on a rib. Yes it gives a great topspeed but that's all it does. On lower speeds and in combination with some load it's the wrong prop.
I am using a Tempest plus 23 and it gives an easy 60 knots.
Sorry, knots must be miles. we have achieved over 100 kmph and that is more than 55 knots.
We have made a better topspeed with an 25 pitch tempest with big vent/holes plus, but acceleration with the 23 is alot better and we keep the vents a bit smaller.
A four blade trophy was much better to handle the boat through rough water but the topspeed came down 4 to 6 miles.
A big prop as a Cleaver or else in combination with a lift will surely give more risc of having less coolingwater but your Optimax has an low water pickup. Therefore you can bring it up alot without having to worry about the cooling. Be ware that this only works safe on flat water.
This pic will give you an idea of lift in combination with a surfaceprop.
