Good morning I bought this 1065 Mustang about a month ago. The first few voyages were dry. Recently I’ve pulled some kids on a tube and now I’m taking on water at a unsettling rate. Looking at the hull, I’ve got a few obvious spots that are getting stressed, the rudder plate, the drive shaft opening, and the deck attachments. Other concerns? cooling system muffler outlets? A couple questions.... can you simply “tighten” the bolts on these attachment plates? Can you pull the boat out and fill the bilge with a hose to identify areas that “seep”? It’s an old boat and likely deserves more respect than I’m giving it but heck I bought it to use it. Any guidance would be appreciated. David |

David, Filling the bilge with water is a good way to find leaks. Go for it, see what you find and report back. From what you have said, the leaks at the rudder port and shaft log may just be from old dried out packing or just needing some tightening of the packing glands.

Thanks for the insight. Curious, what is a “packing gland”? Not a term I’ve come across. David |

David, The packing glands keep the water from entering the hull. There's one on the top of the rudder port and the other between the trans and hull log on the prop shaft. Inside the gland is a rope packing that gets squeezed around the shafts. If you do find out you are getting water at them, we'll continue with some advice and links.

Aha. Found a video from Hayden’s How to’s where he repacks the glands around a drive shaft. Got it. Sorry should have googled before asking. It’s the “why daddy” 10yo in me sometimes. |

So after very quick inspection, I found a freeze plug on the 1965 Ford small block 289 that had rotted through. Bought some cheap Chinese made plug from advance auto but it wasn't very thick and getting it seated was a challenge due to the access angle. I am going to try a brass set from summit and apply a gasket seal. Any recommendations on a gasket sealer? |

If you are installing a casting / freeze plug properly, you shouldn't need gasket sealer... I realize that access can be difficult with body contortions and angles, but try using a big socket that fits the freeze plug. You hold the socket and give it a whack or 2 to seat the freeze plug. This method can make he installation easier. A bit of double-sided tape can also help hold the socket in place on the freeze plug. JQ

Now if one of those plugs rotted away, how far behind can trouble with the rest of them be? And if it rotted away, it probably wasn't brass and maybe the others aren't either.
It's probably a good thing that you bought the whole set for a SBF. If you have trouble getting it in, you can do a temporary fix with an expandable rubber plug that's fairly easy to install and when your season is over you can replace them all with the brass plugs. Some people have been known to leave that "temporary" plug in for a long, long time.  Sometimes they can be a little tough to get back out Here's an example in the link below from the same place you bought the other plug http://shop.advanceautoparts.com/p/dorman-autograde-rubber-expansion-plug-1-1-2-in-size-range-1-1-2-in-1-5-8-in-sold-by-each-570-009/16140204-P" rel="nofollow - link |
