They’re called ‘throughputs’.
But since removing them was frustrating, backbreaking work at the butt end of the boat, I’m more inclined to call them … well, you can guess…
There are five of them. Four are brass and the fifth is plastic. Throughputs are like casements for the actual hole that goes through the hull and are held in place with nuts that screw onto the end of them…which after years of neglect are practically welded to the throughputs >sigh< Various pipes and hoses are hooked up to the throughputs for things like motor exhaust and bilge pump.
Rick is down in the lazarette (aka glory hole (?), on his side, trying to maneuver the wrench into place, while I am on the outside, trying to hold the darn throughput still – to keep it from turning as he turns the wrench.
Utter failure. The screwdriver I’m using just slips off. I try a pipe wrench and learn from Rick how a pipe wrench works: Something about angles of the teeth and starting at the top and rotating downwards, which side to use and way more info that I wanted to learn about pipe wrenches, which doesn’t work anyway because there simply isn’t enough of the throughput sticking out. No way to grip it effectively.
Rick notices a wasp nest has been built in the lazarette of the boat. Lovely. He is watching two wasps watch him. Tension builds.
We have traded tools back and forth for about 30 minutes now, when a neighboring boat owner tells us that there is a special tool for removing throughputs. Well, of course there is… It’s kind of like a key, but heavy and pyramid-shaped.
He is gracious enough to loan his key to us, along with a huge wrench AND a pipe that slips onto the handle of the wrench so lengthen it and gain more torque.
So, now Rick is holding onto the nut on the throughput, on his side, watching the wasps watch him. I place the wrench on the key and insert it into the throughput and pull down on the pipe wrench til its vertical, then push the pipe wrench upwards, down one side and up the other, like a pendulum going from 9 o’clock to 3 o’clock on a dial. Then I have to pull off the wrench and replace it on the other side and do that again, 40 times per throughput, at least.
I am running into the rudder with the pipe handle which hinders my being fully effective at this job. I’m whining about it and Rick tells me to push it out of the way…um, yeah, it’s a rudder, rotating is what it does for a living! Now, I’m really able to get a good swing with the wrench. Put in place, pull down, push up, pull off, put in place, pull down, push up, pull off. Over and over and over and over and over.
On one of my pulling/pushing travels, I notice a price sticker on the tool – it cost $50. Wow.
2 down, 3 to go. Roadblock. The tool doesn’t fit the middle throughput! This one looks different than the others and there is a different tool, for each brand of throughput. Well, of course there is…
So we can’t get the middle one off. It’s less corroded than the others. In fact, it’s not corroded at all, just grimy and tarnished. I’m all for saving it! Just a little polishing up and it will look good as new! I hope.
The other 3 come off just fine, although the plastic one had to be cut off. It was easy to do.
Meanwhile much, much time has passed and reading a novel in my beach chair is not the long, lazy afternoon I planned but only about 20 minutes while Rick is making huge amounts of noise and dust with the saw, cutting off the plastic doohickey. And I’m too tired to read, so I take a power nap.
But, the job is finally done and we are left with raw holes in the boat, so more wasps can find their way in and build nests!
It is interesting that you can leave something alone for less than a week and return to find spider webs and wasps’ nests and bird poop all over it. Ah, nature 😉 btw, Rick just read this post and told me they are called “through-hulls”. Through-put must be a carry-over from my IT management days!
