Re: Evinrude Sportwin bolt thread help needed

[Phil Budne]

Sorry, petrolist for some reason I got the idea you were talking about a pivot bolt on the transom clamp assembly. One thing that works well where you suspect that head bolts will break, is to cut or grind off the head of the bolt, remove the head casting, and weld nuts to the protruding shanks, this usually gets them hot enough to remove without breaking. A shot of your favorite penetrating oil onto where the threads start, to cool them a bit, will be drawn into the threaded area.

Expect to have head bolts break wherever the motor has been run in salt water.
