Ayuh,..... Welcome Aboard,..... With it's age, the odds are the transom is rotten,.....Thank you 88 ... I ran the unit in my drive way with the ear muffs hooked up and no water intrusion. I launch it, dont start it, and that was when the pic was taken of the water coming in, just sitting in the water, no engine running. Should have mentioned that in the first place. Bellows and outdrive have not been serviced in 10 or so years. Use the boat maybe 5-10 times per year, running under 1 hour per launch.
If it does come down to the transom being rotten there are plenty of threads on the site and in the stickies that show and explain what you may or may not be confronted with, plus plenty of people here who have plenty of knowledge to share.Ayuh,.....

If you do the work to pull your drive, engine and transom shield. You are into it for a weekend and you work at your own pacelooking to have someone pull my sterndrive and identify a thru hull leak, and service the outdrive if its not transom rot. 1991 FourWinns Horizon 200, 4.3 OMC CObra
Located in SE PennsylvaniaWhere are you? I did find one old dude near me that would work on the Cobra. Although he really didn't want to, and convinced me to do it myself. I did tow it to him twice to help me with a few specific things though.
I snorted a bit when I read Scott's weekend timeline, lol. It took me more than a year of occasional work, but I pulled everything out (down to the bare keyhole), inspected, replaced some stuff, cleaned up a bunch of things, and reassembled. Even with my own labor I'm in for a few thousand. I can't think it would be remotely worth it to pay someone for the labor, it's a lot of time consuming stuff. And in my case that was absolutely best case scenario because there was no rot. If I had found rot, I was going to cut my losses and dump the boat. Sometimes I wish I found rot.
It was a lot of work, but at the end of the day at least I have a 35 year old boat with an obsolete drive that doesn't like to shift out of gear lol.
