Need help with selecting new prop

[Briatar]

I have a 1990 Stratos 201 pro duel console with a 1990 Johnson 200GT ....prop is a 4 blade renegade 21 pitch and is set at 3 3/4 " off pad with no jack plate.... it's running 50mph at 3/4 throttle and my rpms are 6200 ....so I picked up a 27 pitch Renegade 4 blade and now I'm running 45pmh wot at 4800 rpms.... what should I do for a prop as I've went from one extreme to the other

Trophy+ 25p would be my guess but, it depends on what you want out of the boat? Find a vented 4 blade that gives you top end you want at the rpms you want to turn than adjust the vents to get the hole shot you like.

You are WAY too high without a plate.
I'll bet you're throwing a thirty foot high roostertail.

There is no roster tail coming off the back... not even when I trim the motor
