Yesterday I motored out to some bigger water and had a great sail on a beautiful day. Wind 12-15. Seas 1-2 feet. Really great. Sailed back to the beginning of the channel to head in and the engine overheated again. I have a Yanmar 2QM15 installed by a PO years ago in my C&C 29.
The last time this happened while investigating what could be wrong I opened the raw water strainer, saw that nothing was blocking the water flow and closed it back up, restarted the engine and the water flowed normally. So I figured if it worked last time , it could work again. Yup, it worked.
What is going on here? Is there an air lock that needs to be broken ? Is this going to be part of my SOP? I'm sure that running the impeller dry isn't a good thing.
Has anyone run into this before and/ or have suggestions as to what to look for?
