My 3 blade Gori was over pitched, and after a couple emails they took it back . I thought they would reduce the pitch, but they sent it back to Holland or wherever and took a half inch off the diameter, it was perfect. I was afraid they would dis me, but they took care of it. I would suggest that if you are having that chop-chop sound, go to a 3 blade, it solved my problem.

I doubt getting this Gori 2-blade 16.5 x 11 RH prop rebalanced will help since I already did this and the results we're negative. After trying to resolve this for the last three years I think the only solution is a new prop. I relied on your company's expertise to size this prop for me and I made a mistake that I will have to live with. If you know of anyone that wants to buy a prop please let me know. Thanks for your concern.

Sorry that i cannot be more helpful than that.

I spoke with you at Strictly Sail Chicago concerning the noise I get with my Gori 16.5" x 11 x 2rh prop. You suggested that tip clearance could be the culprit. My tip clearance is 5-1/2". I spread the prop by spanning the blades and hub with a strait edge and measured this distance. I also measured the distance on my 1" shaft from the cutlass to the front of the prop hub which is 1-3/8". My boat is a 1979 C&C 34 with a Yanmar 2QM. The noise is really noticeable and could be a concern if I ever try to sell the boat. Would a smaller prop solve the problem? I installed a new shaft and coupling when I purchased the Gori. I lapped the shaft and checked it with a dial indicator. The shaft is aligned. I really appreciate your attention. Thanks, Chris Tassone 231-946-8185 H 231-883-1234 C
