That may depend on the motor you are using. I have a stock OS I was extremely impressed with a Grim 40/52 ( 3 blade).

However the man of COBRA boats ( Dan H.) says something else. PM him, He is a great guy.

I'll PM you when I have found something better, if I can.
 
hey if that 40/52-3 is the answer than so be. it i dont have one but the next time i go to graves in orlando i will defenetly get one. thanks, Dan
 
Dan, I havent been out to test the one you told me works for you, Cant wait to try it out and others also.
 
wow, one of my head hairs is only .001",, that really is a hair,, won't help much tho.

I can try one of the pewb's, wonder what they would measure?

Thanks Tim i meant to mention it is a O.S. timing raised a hair.
How can it be "stock" if the timing is raised a hair??????????????????

It may not be MAMBA stock legal. But it is IMPBA sport (some what stock) legal.

Jerry you must have frog hair if it is only .001". :D
