currently running a mirage 23. keeps hitting the rev limiter, even full of gas and 6 adults on board, 70 mph GPS...

can't believe it ! what's the right prop pitch so I save time testing? 24 4 blades? 25?

I have a spare 4 blades 28 but I'm sure it would overkill the engine...

what's your guess?

thanks!

Try a 25 mirage +
