Hunter three GM 30
In trying to get my engine on frozen my crank shift and that keeps backing off I was wondering if anyone out there knows the size of that nut and thread pitch so I can order one somewhere in the ideas thank you I'll help appreciate it Christian

I think you are looking for info on a Yanmar 3gm30, which isn't specific to Hunters. You will probably get more hits if you post this in the "Engines and Propulsion" section.

In the parts book, the nut is listed as an "M-18" but they don't give the thread pitch.. it could be 1.5 or 2.5.. Ya should be able to find them at a fastener supplier.. the nuts should be 2-3 dollars each..
