Points well taken and all valid. I appreciate your input and look forward to it in the future. It's good to have others experience to go off of. I commercial fished for 7 years out of a wood boat in Alaska. My first year I thought I would surely die when we put the boat in the water and it leaked so bad that the bilge pumps were constantly running the first 24 hours. After the wood swelled then it only leaked a little. The only thing keeping the pacific ocean from going into that boat was a lot of wood planks, some cotton calking and a fresh coat of paint. I dont think there was an ounce of epoxy on that boat. Things got better when I moved up to a fiberglass and then an aluminum boat. I guess I do lean a bit to the side of overkill but than again the ocean scares the hell out of me. [img]/images/graemlins/grin.gif[/img]

Thanks again

I am going to be putting a similar through hull in my 20 foot project. I have never had a through hull with strainer before. The open strainer portion is mounted facing the bow? If the strainer faces the bow do you install a valve to control the water flow near the bait tank so you can regulate the flow when underway? I will be instaling a seacock as well but think a valve near the tank may also be needed? I plan on mounting the seacock to marine plywood that has been wetted out with epoxy using a slow cure hardner. I think I will drill holes through the plywood allowing access to the bolts holding the strainer to the hull (so you can use a deep socket to remove if needed). I am trying to figure out the best way to make sure the holes in the plywood (to get to the strainer mounting bolts) have a way to drain water that may accumulate in them so it does not sit too long...or perhaps I should just cover with 4200? I plan on bonding the plywood to the hull with thickened resin, but I do not plan on covering the plywood with fiberglass cloth. I will be using a shurflow pump with dual outlets for baitwell and washdown applications.

Recommended mounting position for the through hull in the 20?

I would appreciate any feedback on my plan or advice to improve.

Thanks....John

Yes mount it facing forward. Don't put the little wire mesh thing in it like I did as I keep catching hell for doing that. Put a strainer on top of the seacock. I have a pump that mounts to the top of the seacock which is why I did not put a strainer there. Get a pump that you can mount somewere else and run a hose to it from the strainer. I like your idea of drilling holes into the block to reach the bolts on the scoop. Yes I would fill with 4200 or silicone that you can dig out later. It cant hurt to put another valve by the bait tank. I usually just turn off the seacock when underway. You can also partially close the seacock and get the same effect as putting another valve by the bait tank. Sounds like you have it all figured out.
