I made an offer on a 1981 Super Sport 42'

I have a 42’ 1981 Ocean , just posted a pic of it under Ken’s “ Happy Thanksgiving post “

The port holes are factory original .
Ocean later did away with them soon after. I would leave them be. Just check the sealant around them where they meet the hole on the outside most likely I would rake it out and re-seal them which I have done with mine.
We enjoy the sun light and fresh air the offer.

Go over your rub rail and hull to deck joint for leaks from with in the bilge.
I’m sure you got them . Generally you can only find them in a heavy rain storm at the dock while you creep around from within the bilge and a bright flashlight to see them.
Ocean used a teak rail with stainless rub rail screwed over the teak base which over time pulls away from the boat and leaks.
It’s a notorious spot for leaks on the older oceans.
Double check your fuel tanks especially on top for any rust or holes including the deck fills ,the pipe running down to the fuel tank if they are original they might be leaking also.
My fill pipes were rusted badly and I had to replace them.
My fuel tanks are original and still ok.
Luckily.

I had to reseal my deck joint and install a new rub rail to stop the leaks.

Check the trim tabs where the fasten to the hull. The fasteners , if not replaced already, are probably going Bad from corrosion and will need replacement.

It’s a good boat . I enjoy mine thoroughly and use it all the time.
They just need a little TLC when they get older. Which is to be expected.

Look under new posts …

Yup…no blood and guts (fish)on my boat unless they’re filleted , ready to cook for a civilized dinner.
I’ve got a 22’ Chris Craft for that mess.

I have a post on here on how I did my rub rail and what I had to do a year ago or so.
As everyone knows I’m not very computer savvy but on YachtForums search type in 1981 Ocean Yachts rub rail it should pop up.
You will see what you’ve got.

Check all the salon windows for leaks, rotted wood behind the couch. Every ocean has leaky windows

I have sliding windows, which I have kept in good working condition. BUT, they needed TLC when I got the boat and then some. It is not paneling but structural plywood with vinyl commercial grade wall covering over the wood which you can get from your local wall paper/paint shop.
I did not rip all of mine apart. You quickly can get to the point of no return and a huge never ending problem. I had some rot under the slider track. I used M.A.S. penetrating epoxy under the track and let it soak into the wood. It works well, good stuff. You can thin it with acetone to get it like a water consistency so it really gets around. It varies for me to thin or not, depending on what I'm working on. Leave it thick to plug up leaks. Make sure you add a little at a time around and under the track, not in the track or your windows sure won't slide anymore!
Then sealed up slider track with 5200.

So far so good. You must at least twice a year , service the water drain hole at the end of the window frame that comes out the side of the window/wood frame. Make sure the drain tube wall is sealed with west system / epoxy. Make sure it's always clean and clear of junk along with the window track . Make sure it's draining all the water out.
The drain hole or holes are small and easily get clogged up. A small plastic tie strap shoved in the hole from the outside along with a shot of pressure water will clean them out.
I test mine every time I wash the boat.

If I were you, I would keep them in if they are in ok shape. Just put a little love into them.
New windows are big bucks. AND nothing is ever easy.
I know you will need that money elsewhere.

I have a 1985 42' Egg Harbor and I am currently replacing an aprox 3'x4' piece of teak paneling in the salon from window leaking damage. Just knock or tap on the paneling, it will sound hard or soft, soft is bad. Not impossible to replace but not much fun either. Enjoy!

Did you guys get a good look at the fuel tanks? Especially the tops of them? Leaking deck fills/pipes/rubrail and such can cause rusty problems/holes with the steel tanks.
My tanks were glassed in from the bottom up and just over the top by Ocean. Your boat is probably the same.

Steel. Maybe black iron.
But steel of some sort.

Rust and rusty flakes ….
Ocean used steel fuel tanks.
At least on their older models.
I don’t know about the newer boats.
Monel…made me laugh!
I wish!
