I have an overheating issue. I have dove and made sure throughhull is clean, strainer is clear, replaced impeller, new mixer elbow and fitting. It is spurting water out the exhaust. It’s raw water cooled, no heat exchanger.
My next job is to pull the thermostat and check it.
My question is will a thermostat cause it to overheat even if I’m having flow out the exhaust.
I’m also looking for a service manual for an 1985 yanmar 2GM
