On a 1980 C&C 36 with a Yanmar engine I experienced a cooling water blockage underway (bound for Seattle from the San Juan Islands). After checking the usual suspects and not finding anything amiss I focused on the raw water intake. When I pulled the raw water inlet to strainer hose a golf tee shot out of the fitting. A frick'n golf tee got sucked up and stuck fat end down to effectively block the flow.

I would second that advice. Thought I had an elbow or water injector problem once but it turned out to be a partial sea water clog that was entirely confined to the hose barb going in to the sea water strainer. Couldn't see it. Took off the hoses, took off the bowl, all seemed ok. Thermostat was stuck, so I ordered a new one. The top part of the strainer was secured to the boat, and I didn't take it off until much later, which made the problem relatively easy to see. Partial flows can be deceptive.

Thank you all for the info. Figured it sounded like constricted flow. Gonna get the elbow and nipple replacements first. Then pull it apart and replace them. Agree no sense putting back the old ones. thanks again, Jim Galaxy 34'
