You're power plant is pushing your current 21P to Max RPM. Dropping to a 19, your going to be able to push a 5 blade to max RPM so no worries on going with a 4 blade if that's what you choose. I haven't owned a 4 blade prop but did operate a friends 21 foot Chaparral that had your same 5.0 GXI with a 21P 4 blade on it and it did well. Can't say that I noticed much of any difference with it over any 3 blade prop I've ever run. Have been told that the difference comes in when you have a boat that is underpowered for its size and is tuff to get on plane, dropping an extra pitch size like a 17 pitch instead of a 19 and going with a 4 blade vs a three blade makes a noticeable improvement. Was told this by another friend who had a 22 foot wellcraft powered by a 4.3 carb engine that had a tuff time pulling folks on skis and often had to put everyone in the bow if he had a boat load to get out of the hole. He claims when he ran a 17P 4 blade that his problems were solved but he did loose a bit of top end speed but that was expected. Summary: Think a 3 blade 19 will get you the improvements you're looking for..

i have a 212 rinker captiva rx1 that came with a high five prop 21" pitch, it was ok but we found a sunken barge and there it went....so I searched to find a good prop for my boat, it has a 350 mpi at 300hp with a 2.0 gears. I tried a four blade 20, 3 blade 21, 4 blade 19 all of which had it's place but not for me. we do a lot of tubing and wakeboarding with some skiing so hole shot is a must and we are FULL with 10 passengers so I also need grunt power at any speed plus I like to open her up now and then, I found a 5 blade pleasure prop from ron hill in a 19" pitch... LOVE IT it does what I want and need with a full boat skiing, wakeboarding, kneeboarding and tubing all in one prop. my 2 cents worth... similar size and close hp. iy might work for you too...
