have a 21p but will another one be better?

[Jhunter]

I am running:

2002 stingray 200lx
volvo 4.3 gxi
volvo sx drive 1.66 ratio
wot 4400-4800
3 blade 14.75 21P
top speed about 60

Used for wakeboarding, skiing, and tubing. Was wondering if a 19 or 17 pitch would do me better as far as coming on plane. If so which would better. I have scoured the search function looking for a boat similar to mine but can't find anything I feel is a good comparison.

If my memory serves correct its pretty close to 4800.

Since you are close to the max rpm's it is an excellent indication that you have the right prop.

If you go to a 19p, then go with 4 blades instead of 3 blades. You may have to go easy at the top end of the throttle range so as not to over-rev.

With your present rpm usually it is suggested to go to a 4 blade and drop one inch of pitch to maintain rpm.
The 4 blade should get up quicker,stay on plane better at reduced throttle and respond better.
You will likely lose some top end.
