Re: Catalina 27 Maintenance - Where to start
If you are still on the water and want to putter, I would spend time rebedding hardware and focus on anything that appears to be leaking. Oil you teak just to keep it fresh and good looking. Oil and fuel filters etc are annual. When you do change oil, flush the engine with new oil, a couple of quarts to make sure you got out the old dirty stuff. Don't forget to clean the fresh water strainer. Do check the alternator belt and all hoses for cracks. If you find that the head tends to get back flow into it you may need to replace the back flow valve.
