We were excited to get the boat in this last weekend after repainintg the bottom, replacing the tiller, resealing the rudder seam, repacking the stuffing gland with Duramax Ultra-X, and having pros replace the cutlass bearing, reseal the knotmeter thru hull, and change the gasket on the diesel tank. Money all well spent for a safe new season.

Until... the boat was hoisted in and a leaking/seeping seacock was revealed in the v-berth. This is the one that the sink drain leads to and also provides intake water for the toilet. So we will have to pay for another hoist out and in, and the repair. Catalina Direct sells a seacock repair kit including two backing blocks, and they say always use a backing block when installing a thru hull. Though I have backing blocks on the knotmeter and depthfinder thru hulls, there doesn't appear to be backing blocks on my original seacocks for the two sinks or for the diesel intake. Does anyone know the scoop on the thru hulls on an 88? Why are they glassed in instead of on backing blocks? Or is there a backing block glassed in too?

Does your boat go on the hard in the winter? If so, perhaps you could make a temporary repair (for the season) using epoxy that cures underwater.

Yep, on the hard every winter. So, hire a diver to apply from underneath? Or do this from inside the boat?

Do it from inside for the season.

<< a leaking/seeping seacock was revealed in the v-berth. >>

Where does it appear to be leaking from?

I might work on the seacock in the water after putting a cork in the outside, and right next to the boat lift...

One thing to consider - is the leak a result of a crack and the thru hull is about to break off? I'd give it a gentle wiggle - while having a plug on standby.

I would apply the epoxy from the inside. This is just to get you throught the season.

On your boat is this a "volcano-style" through hull, or something more substantial? The volcano style ones are literally a cheap pipe nipple that has epoxy piled up around it. They are not very structural and if one has started to weep then I'd replace it. If it isn't leaking (see below) then I'd leave it alone, but put it on your list of things to replace next year. I would only keep soft items (like extra PFDs) in the v-berth locker until it is replaced.

Finding a puddle around that through hull doesn't mean that the through hull is leaking. Often it means that the drain on the anchor well is blocked and that the anchor well has filled with water and that it is leaking down inside the hull.

Thanks, everyone. The seacock is weeping, at the base. It is not condensation or from the anchor locker. We can watch it weep in. It looks like it is just glassed in.

They are pulling the boat today and replacing it. I wonder if I should have the other two replaced as well. They aren't leaking, but they look the same, just glassed in, and with no backing block. Were they not using backing blocks yet by 1987 when the boat was built?

I'd replace the other two as well. They will need it at some point.

This is one place where Catalina took short cuts on these otherwise nice boats. Most boats made during the same period from other manufacturers had properly installed seacocks (the best option) or at least mushroom head through hulls with ball valves mounted on top (that's what my Pearson has).

Yepper.. that would be pretty much near the top of my list.

I replaced all three seacocks the last several years ago because I knew the originals were dangerous. A friend who knows his stuff and lives on his boat helped me. But I have the same issue with the one under the V berth. I assumed it was leaking but not sure if it is from the anchor locker as suggested. How can I test it? It is in my yard and not going anywhere any time soon. Thanks.

Replacing one seacock parallels replacing one brake cylinder.

Does your anchor locker have any water in it? If so assume that it is leaking, and the first thing would be to clean out the drain.
