Fresh water flush Yanmar diesel
Can anyone tell me how to fresh water flush my 1985 G3 27hp Yanmar diesel. It''s not circulating enough water to keep the engine from overheating.
I have cleared the raw water intakes on my saildrive, checked the pump hose to make sure its clear, pulled the water pump and inspected the impellar and looked for debris, and the water still trickles out.
The only other thing i can think of is buildup in the engine.
Any and all thoughts welcome.
Thank You, GG (Charleston, SC)
