    Hello All!

    I'm new to POST (SportsFish at that) and new to this forum. After many year of running outboard powered boats I finally bought a 1975 42' with JT 671N. Needs some major TLC, but hull is structurally sound and engines have been recently re-manned. Going to be prepping/painting the week after Xmas along with new rub rails and anodes. Will also replace the cutlass bearings and impellers while its on dry dock.

    Will update as we make progress and plan on posting plenty of pictures. Advice and feedback is welcomed!

    welcome aboard.

    that's a real nice looking Post

    I like the spray rails up front.

    please post before and after pictures of this classic for the rest of us to enjoy.

    The boats lines are timeless.

    Congrats Capt!

    Anyone here knows the foredeck core thickness? I have 2 spots where the tuna tower attaches to the deck that has some rot.

    I think you will find it's not "cored" but actually fiber glassed 3/4 inch plywood.

    That's what I was thinking by "core". Didn't know if I was dealing with balsa or marine ply. Thanks! You saved me an "after pulling the skin" trip.

    Bob is correct: The 75 and 76 had Plywood for a deck with a glass overlay. The balsa core was done on the 77 and up.

    Curious, why so many vents on the hull? I'm considering filling and fairing the forward 2 and perhaps enlarging the ones closest to the stern. Are the six total (starboard and port) all vents used for the bilge/engine room?

    I agree, the older Posts sure do have a lot of hull vents.

    I like the idea of consolidating the vents if possible.

    It makes the hull look updated.

    Just be sure to maintain the necessary air volumes for operating the engines and genny

    Hi Dan: I took the two vents out myself and filled in. I had the 671n and re-powered with the TIs. I made the vent look like the 8Os model. There was more than enough air coming in with the one vent. The Turbos are going to pull more air in than the Ns. You will not have a problem changing the vents. I will send a pic of what I did.

    Thanks Shawn! I seen your boat on the other vent thread, did you custom make the vent? I'm planning on converting the current vent closest to the stern into a single long skinny vent like the 2000s post. Will send pics early next week of my progress.

    It is common for downeasters to have the air intake inside the cockpit and no vents on the hull.

    I am familiar with one boat that has a C-18 and generator. That boat has an air intake of approximately 2 square feet in the cockpit and no hull vents.
