It is 18 5/8

Who did you work with to get your prop rite ?? I have a new #4 with a big shaft right hand new ratio, talk about starting over. Any help would be great !!

What kind of boat and what gear ratio do you have ?
I got a #4 also ,maybe i can help you ?!:rolleyes:

Its a lite triple step 30 Super. The ratio was 1.68 left hand, but now a 1.5 right. Drive is 1&3/4-2 below the bottom. Worked with Brett on this and he was the best until it hit something and took out the prop and drive. So going to have to start over the old drive was a small shaft. To really get it rite 14 degree of rake is not going to cut it. All cleavers have almost the same degree of rake. But lifters !! I need the nose up. Ive played with spacers on the old setup to no avail. The only thing that the boat really liked was diameter. 17.5 to 18. Rite now I dont have 5k for a custom 21 degree rake wheel. So im going to hunt for an 18 x 30 3 blade to work with. Unless you have some other ideas ?

I had a local guy here work on it in Oklahoma. Did a great job and the boat FINALLY runs like it should! :cool: JCPERF has a good guy on Long Island that did one of my other props. Nice work!
