thruhull

OK, this is kind of last minute but here goes. My boat is currently on the hard. The engine intake thru-hull is being replaced (amongst other things!) The one removed had a screen similar to the one here...

I recently removed the original waste outlet through-hull. It is is 1-1/4 inches. The norm, I believe, is 1-1/2 inches. At any rate, on my boat someone in the past used a reducing coupling to join the toilet's 1-1/2 waste hose to the 1-1/4 valve on the 1-1/4 through-hull. Not sure why they would...

I am in the process of upgrading the electrical system and electronics for my E25. I'm thinking about purchasing the new Garmin GPSMap 541s while the $100 rebate is in place. I'm looking a several different thru-hull transducer options. The existing thru-hull is about three feet forward of the...

Hi everyone, Our insurance company has asked us to replace the pvc elbow on the pump-overboard thru-hull on our boat. I know some of you have already done this. To save time and money, I was wondering if anyone had simply "unscrewed" the pvc elbow from the thruhull, and replaced it with...

Seth wrote in another thread: Seth, et al- I'm in the process of doing a major overhaul on everything below the waterline (peel, barrier job, replacing all and relocating some thru hulls, etc). A couple of questions for anyone who wishes to comment: 1) I contacted Centek industries...

E23-2 1975 just foward of the mast post in the cabin between the post and the foward berth housing there is a small square panel. Pull it up and you have a large plug with stopper in it. When you pull the plug it looks like the whole lake is flooding in!!!?? what the heck is this plug for,,,is...

DIY Vikings, Somewhere on the board there is a thread that describes replacing these four aft thru-hulls on an E38. I couldn't find it tonight. The picture attached shows the seats of the flush thru-hull holes. The thread I was trying to find described rebuilding the seats with some kind of...

The fitting in the picture was removed from the intake side of the raw water strainer, It was mounted on top of the raw water thru-hull valve. It seems to be a safety device, but I don't understand the exact function, how to activate it, and why it is safetied the way it is. The last time I...

I'm thrilled to say that today I was able to reach and remove the old thru hull to remove the original (I think) gate valve! Quite a tight fit behind the sink on my E27. Now, I need to replace it all. the outside of the thru hull had a small grate over it (had to destroy it), I presume to...

This weekend I was in the process of wrapping up a long & tedious series of projects. The last of these was changing hoses to the engine (Universal M25). Upon completion, I turned the marelon ball valve for the seawater inlet. It resisted, then gave way & seemed to turn too easily. The shaft to...

Recently purchased a 1969 Ericson 23 with a thru-hull rudder assembly. The tiller mount fits into the thru-hull fitting and has, incorporated into one piece of metal, two "pin mounts" (small holes for a bolt to slide through) for the tiller. One of these has been broken off (as can be seen in...

This winter I am trying to replace all of the thru-hulls and sea cocks on my E-29. I am having a problem removing the 1-1/4 sea cock on the starboard side. I have removed the bolts but the sea cock was glued in place with what looks like 5200 or silicone. Either way I can't turn the valve. Can...

I was hoping for opinions on bronze vs. plastic thru-hull transducers. Raymarine told me to use plastic for fiberglass sailboats. Others have stated that they only put bronze through their hulls. I am pulling the boat for a bottom job and want to replace thru-hulls with the appropriate options...

I just discovered that the only gate valve on my 1973 E-32 which was not replaced by a PO was the head discharge outlet. Can anyone tell me the size ball valve I'll need to replace it, and whether I can just unscrew the gate valve and put a new threaded ball valve onto the thru-full fitting? I...

I found this photo from two years ago when all the original Marlon valves on their threaded thruhulls were replaced with the "newer style" Forespar base-mounted valves. The new ones are epoxied to the backing plates. The marlon threaded thruhull pipe is screwed in from the outside, and bedded in...
