    Intake Thru-Hull, Screen or Not?

    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...

    anybody else have 1-1/4 inch waste outlet thru-hull?

    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...

    deadrise for thru-hull

    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...

    PVC Elbow Thru-hull Replacement

    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...

    Cockpit Drainage and Thru-hull Questions

    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...

    Thru-hull installation

    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...

    What is this? (part one) - Thru-hull

    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...

    thru-hull for water to engine

    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...

    Ball valve & thruhull

    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...

    WANTED: Tiller mount for thru-hull rudder

    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...

    Thru-hull removal

    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...

    Bronze vs. Plasitc Thru-Hull Transducers

    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...

    size of head thru-hull valve?

    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...

    New Strainer & Thruhull

    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...
