Gasket lined up and fit perfectly on 1979 Johnson 35hp. No leaks. I’m very happy and shipping was on time as projected. Thank you.

Worked great!
No leaks even with two snapped off bolts. Be careful when removing the bolts, i was working on an engine that sat for 20 years, sprayed the bolts with blaster for 2 days and still rung off two bolts.
