    Gen-Sep install.-gctid378005

    My neighbor installed a Gen-sep on his 1969 44 foot Egg Harbor. I inspected his install and he fired the old Genny up, wow it is very quiet. I have decided to take on this project myself. I am going to re-use my Vernalift muffler and just add the Gen-sep. The moorings in LA at the Island are pretty close quarters so firing my obnoxious Westerbeke at 7AM to brew coffee is just rude. (I do not have an inverter).

    I have to mount the Gen-sep to the transom wall up-high near the exhaust loop. This unit will have some pressure running through it and I am a bit nervous about using tiny screws to mount it. I certainly do not want to bolt through the transom and have ugly screws visible next to the "Reel Joy" decal on the back.

    My idea is to use a couple pieces of wood maybe 1 x 4 or 2 x 4 and glue them to the transom, then mount the Gen-sep on the wood..

    A couple of questions:

    Do you agree with gluing the wood to the transom for the mount? If so is a 2 x 4 to heavy? Also, should I use epoxy or 5200 or what for the wood to fiberglass stick?

    I am not a mechanic and have dealt with engine hoses, to me they are a pain in the A**. I will have to run new hoses and cut a new hole at the water line for a second exhaust through hull. Is there a trick to getting the hoses on to the through hull, muffler, etc? My thoughts were to oil the end male pieces and to heat up the hose so I can get them on? Any advise on this is much appreciated.

    I will photo the entire install and document it here in-case someone else wants to do this upgrade. I am hoping to get this done before Memorial day weekend..

    As always, all opinions and advice is welcome and appreciated.

    Bryan,

    I'd be interested in how it was done and photos.

      The transom is VERY thick. I would use #12 x 1" screws if you're screwing in flat stuff like a mounting tab or hose loop, longer if it's a thick item. Getting 3/4" of bite from a #12 screw into the transom is going to be SOLID!! Or even a #10 for lighter stuff. Both of those are perfectly valid and strong ways to do this. I would use 3M 101 or 4000 to seal any holes, definitely not 5200.

      Your idea to provide a backer board is good when you are putting in a bunch of screws in a small area, so you drill only two screws into the transom and all the others into the backer board. But in this case I really don't think it's warranted.

      Now on this Gen-sep thing...am I understanding correctly that what it does is quiet the burbling of a wet exhaust? I've never found that to be objectionable. I have a 2001 Westerbeke 4.5, and while not silent, I don't think the exhaust is awful. What I don't like is the amount of engine noise it produces in the cabin, particularly the aft.

        You will like the Gen Sep, I have one and it makes a huge difference. Unfortunately I haver no pics and the boat is rather far away right now. I used and additional piece of plywood glued to the ransom with 5200 as adhesive. Wish I could help more.

          Carlos,

          Thanks for the info...

          Here is a link to the Gen-sep. It separates the water and gas. On my neighbors generator the engine and the exhaust were both very quiet. I will take a quick video of my Genny before & after so you can see for yourself the difference.

            This will not quiet down the generator itself, only the exhaust note. What is does is it gets rid of the "sail boat burble" as I call it, so basically all the water runs under the water line and the exhaust is above which is now just a hiss rather than a noisy repeating burbling sound. I went one step further and put on a sound shield, this definitely quiets down the generator itself yet does nothing for the exhaust note. Combine the 2 installations and you are as quiet as it will ever get.
            Cheers, Hans
