Starboard Lazarette Seacock I

With the new engine seacock in place and working well I decided to turn my attention to its counter part, the starboard side deck scupper and cockpit drain seacock.  This one is also two inches and it is accessible from the starboard cockpit lazarette.


It looks like someone took the time to replace this one at some point as it was not frozen solid and it looks to be a quality made bronze ball valve coated with some other sort of metal.  However, as some readers may remember from Stubborn Seacocks, I have some pretty strong feelings about in line ball valves below the water line so it had to go.

On the outside, the thru hull was covered in epoxy and layers of bottom paint.  I cracked it open with my pocket knife and found that the entire interior was saturated.  Not good 😦

I then went back inside the locker to loosen the bronze retaining nut that was on the thru hull.  This wasn’t easy to do in the confines of the lazarette but it wasn’t too painful.


With the retaining nut completely loose I was able to easily push the thru hull down and out of the hull.  This created a gap in between the thru hull flange and the boat that I could get an angle grinder in and cut off the flange.


With the flange removed, I was able to easily pull the ball valve into the boat.  Not surprisingly the wooden base that was supposed to help support it was rotten and came up with the threads as I pulled inwards.  There has been at least one case where an owner accidentally hit this ball valve in their boat the it broke off all together!  As he put it – “a boat sinking situation!”  I agree and am not interested in entertaining that as a possibility.

Here you can see our brand new Groco BV series flanged seacock on the right along with a new thru hull.  These are not cheap but they are worth every penny as insurance against loosing your boat!  I still remember the day my Dad told me that these were the type of seacocks I needed to buy.  I looked at the price, did some quick math, and said NO WAY!!!  However, while the truth may sting a little at first, it is always better in the long run and I will gladly pay the price for our families security.  I wish Forespar made a marelon flanged seacock of this size but unfortunately they do not. 😦


With the old out of the way it was time to make way for the new!  I grabbed some thick construction paper and used the new seacock to make a template for the oakum wood base that will support the flange and house the silicon bronze bolts.

Once the template was transcribed I got to cutting.  I know there are fancy, purpose built tools that could make this job a lot easier but I just have never been able to justify splurging.  For some reason I have always really enjoyed a hand saw and find that I can get by pretty well without much more waste.

Sanding down the rough edges is easy 😉

And here you can see the difference between the old base and the new.  I think the new will add just a bit more stability, what do you think?
