Well, I think I jinxed myself by taking about possibly selling my boat last week. Went to start her up last weekend and the starboard manifold has a couple small water leaks. I have heard some minor leaks can be patched with JB Weld or something. Any advice on how to make sure the leak is not getting into engine??   And how can I tell if it is repairable vs needing replacement?

This happened cause I haven't been able to get the damn brass plugs out to drain properly. I've been fine for 4 years but we have had 50 sub freezing days this winter and mother nature won…

If it is cracked, it needs to be replaced.

this may be the same thing, but it's very small slow dripping leaks right in the middle of the bottom of the manifold. I'm not totally convinced it was caused by freezing. Maybe it has just rusted thru since 1976.... Anyway, one of the guys at SKIDIM mentioned the patching was possible.

You could patch it but if it cracked on the outside it probably cracked on the inside too. Pressure testing is the only way to get a good look at it.

I told you you'd break its heart if you sold it!

This will teach you to ask questions and do a site search for the problem! The issue has come up several times!

Greetings from a fellow Southwinder:

Perhaps you do indeed have internal manifold issues, but I encourage you to not overthink it:

a few years back had a visible leaking manifold crack on my 40 year old 351. Removed manifold and ground crack down to a V. Applied generous helping of JBWeld. Has held up just fine for years ever since, best 15 bucks I ever spent. I posted photos at the time, can't recall the thread name, but also have photos available on request.

Take it off and test it. If it isn't cracked internally save money and JB weld until it leaks again then replace, Or just replace since you are selling it and the future owner won't have any issues.

Use anti seize when you install the new brass drain plugs for good measure. My boat had it's original steel plugs in it up until this last summer. They were so rusted away the threads would still grab but water began leaking by. They were never stuck once in the time I owned it using anti seize.

Someone probably over tightened the drain plugs at some point. Most people don't understand how NPT threads work.
