The drain screw on the aft of the exhaust riser on my 1990 has started a very slow drip when screwed in. I fear it is stripped. It had not been removed for probably 10 years until I needed to twice for a 30 second plus nonstart. Today it started a very slow leak that is worse when she is cold. A couple of options, it seems, perhaps someone has a better idea:
1. Since you can get by without removing it often, use a tiny amount of a liquid gasket product to finish the seal and hope you can break the tension if you need to drain the riser box in the future. Downside, you'll have to break the seal and hopefully not damage the screw in doing so. Perhaps only apply to one thread.
2. A small wood plug. This seems like a really bad idea.
3. Buy a new screw drain. Problem: If the female side is also stripped, this will not solve the problem.
Would love to hear how someone else might have dealt with this before.
