Hmm...a 33 year old Clinton-based outboard is no prize. Parts are difficult to find, and the engines are noisy, vibrate a lot, and don't push your boat as well as an equivalent OMC or other major outboard.
They're cheap, though. If yours runs OK, then use it until something breaks on it. If it's an easy part to find, fix it and use it some more.
There are a bunch of them out there, so finding another one as a parts donor isn't a bad idea.
Bottom line is that it's old and it was never much of an outboard to start with. If it suits you, use it as long as you can keep it running.
Best of luck!
