Prop /wheel advice

[nwcjd]

Hello all, need to drop down from s 30 to a 28 for clearance/cavitation issues,that are shortening the life of current one. Current performance and rpms are good . Looking for suggestions in going from 3 blade to a 4 blade dqx,dropping two inches in diameter and questioning the right amount of added pitch. Thanks all!!

I would call Nautilus or H and H ,or someone in the wheel business and talk to them.They do a lot of different applications and have a lot of baselines to go from.

Thanks, I have gotten some numbers from them as well, just getting as many ideas as possible before making the jump.

I have had a dqx on my last two boats,and had to drop down an inch of pitch as compared to the dyna quad that was on there before. These were all 4 blade wheels.
