1985 wellcraft 23 nova xl. V8 5.7L 260hp Its has a 3 blade 19pitch what would be a good prop for this boat for a little more speed or all around better.

Labbed mirage+.

I have a 21p Stiletto Prop I ran on a boat very similar to yours with a 5.7/260 Alpha. I tried a 21p Mirage+ but it dropped my RPM way too low. This one would hang right about 45-4600 rpm at WOT. I saw 50 mph on gps pretty steady with it with 1 or 2 other people on board and 1/4 tank of fuel. Let me know if you're interested. I only used it for 1/2 a summer and it's in almost brand new condition, no dings or cracks and still has most of the original sticker on it. Looking to get $250 for it.

I have the Stilleto and Mirage series propellers available for testing if you are interested.
