'78 CD 28, with MD7a.
There are 4 small holes around the base of the water pump that drip water. The manual says they are drain holes.
Are they suppose to drip to avoid freezing in the winter and/or airlock? Or do they leak only when the seal stops sealing?
had the boat for 15 yrs. and it has always dripped.
Changed impeller last fall and found the holes. i always thought the gasket between pump and engine had a small leak, so just now noticed the 4 drain holes.
Any suggestions and/or advice?
Thanks,
Doug
