Re: piston stop for 150 evinrude
Let me add....
I highly recommend that you DO NOT install this tool and then turn the key!
I did just that. Installed it, got busy with something else, came back thirty mins later, and for some stupid reason, turned the key.
Engine spun 350 degrees, hit the tool, punched a hole in the piston, and knocked the threads out of the spark plug hole in the head.
Needless to say, I was not happy.
