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.
