Don't go all together with slip. Only go with the way it runs and the top speed. That said, if it runs 5% it's really running with more than the actual prop pitch. Just my opinion.

Don't most props these days have progressive pitch? Would some of my '28' blade area be less than 28 and some more than 28 pitch?

Here is what the calculator says about the props I have ran on my 2 seater:

32 Bullet Cut Performer 4 (Stock 300xs)
99.8 @ 5660 = 5.71%

30 Hydromotive X-O/B (DBR 300xs):
99.0 @ 6100 = 7.43%

29 Hydromotive X-O/B (Stock 300xs):
98.0 @ 6150 = 5.97%


I will say the 32 and 29 were with a stock 300xs solo with my normal fishin load, the 30 was with DBR 300xs and a solo 2 man fishin load. With the DBR kit I am spinning the 29 to 6400+ now.

All of the above runs were maxed out at even with the pad, ive successfully been as high as 1/2" - 3/4" above since removing the LSS2 transducer from the skid planer but it has been too windy to make any passes. I'm expecting to pickup another 250-300 rpm with the additional engine height IF the hull reacts nicely at those heights.

With the DBR mods, I picked up an additional 300 rpm in 100 degree air.

I wanted to make a few passes with your old 30 X-O/B today but the cold front that pushed through last night has the wind blowing. I feel like that prop will be good for 102ish @ 6400+.
