Seacocks for Bay Boat Transom Thru-hulls
Posted on 4/15/21 at 9:33 pm
Posted on 4/15/21 at 9:33 pm
I am wanting to replace all of my thru-hulls with seacocks. I am only familiar with the big bronze flanged style and don't have enough room between the transom penetration and the floor to fit one of those. Do any of you new fancy boat having baws have any information on a tight-clearance style seacock?

Following, I have 4 that’d I like to have for added safety concerns.

Right now all I can think of is a bronze mushroom thru hull with a valve threaded on. I think it'd be better than nothing since nobody steps in the bilge I'm not worried about breaking it off, But I'd like a proper bolted on seacock just so I can bear down on the valve if I need to. It's just so tight down there. I'm not sure why Kenner felt like they needed to put the penetrations almost on the hull. They don't pick up when running anyway, so why not put them halfway between the hull and floor and put a real seacock?
Stuff like this makes me hate bay boats, along with having shite for bilge access.

I've been fricking with a washdown pump on a Pathfinder for 2 months now. If I can't get it done this week, I'm deleting it.

How much room/clearance do you have between the thru-hull fitting and the deck ?

Right at the transom/hull joint maybe a half inch.
Only thing that looks like it would fit are the spartan ones, at about $350 each.

How many would you be installing ?

I just took mine off and capped the connections last year (bluewave). I never really used it.

Think of it as a one time insurance premium -- plus it might (slightly) enhance the value/attractiveness of the boat if you ever sell it.

Check out these tri flanged ones Amazon Link
The forespar marelon thru hulls look like they might be a little smaller too.
You could also plug the transom holes and put your seacocks through the bottom of the hull.
Edit: Do you feel like you need seacocks because you have protruding thru hulls? i feel like if they are just mushrooms, a stout bronze or stainless thru hull would probably never break off.

Partially that, but I had a livewell pump housing break once and took on a bunch of water pumping into the bilge before I figured it out. I also barely sleep at night when I leave the boat in the water. Seacocks would help that

I understand, I think I would plug the old holes and go into the bottom or use heavy duty thru hulls and double clamped connections. you could also get a valve that threads directly onto your thru hull so you have a valve upstream of the livewell pump. Thats if none of the seacock on the market fit.
Groco also makes a small tri flange like the one i sent.

Whenever I redo the transom I will do them through the bottom way out towards the Chine and only have the bilge drain through the transom.
I found this forespqr model 93 "thru-hull valve" which looks appealing.

I was just about to post that. I think if you threaded it down tight, it would hold if something snapped down stream. probably not as good as a normal flange, but better than nothing. They are OEM but there are some on great lakes skipper.

Think imma try a set of those and 5200 them bad boys down. Pretty sure those will fit and last until im ready for a transom job

cool, share some pics when you get it done. I'd looked into marelon stuff a while back for aluminum boats and they seem to be well reviewed. The complaints were from people who didnt exercise the valve for a very long time.

All boats especially offshore and some bay boats are a battle doing any kind of bilge/wash down job. The older the worse the access is my little 19 carolina skiff is the only exception that is quite an all around awesome boat and simple besides getting soaked in mild chop ??..

That looks to be the case and seems to be a way better option than ball valve on thru hull.
First project is cutting a hole in the floor for a hatch so I have some room to do this shite.
