Please let me know if you can help mi with the Mercruiser 6.2 engine cooling.
Regal 26 Express yacht, 2017, Mercruiser 6.2 engine. 230 mg
I was sailed the yacht in 2019 in the Adriatic Sea. There was no problem.
I was not saild in 2020. I made yacht service. I drained water and filled glycol filling.
The pump implerer was replaced. After replacing there was some a problem with the pump drawing the water and the engine was overheated on the land.
In 2021, the engine worked properly for 10 minutes after I put the boat to the water.
Leaving the port after 10 minutes, making a 180-degree, 10kn turn, I heard bubbling from behind under the aft platform and noticed white / gray smoke from under the platform. I also heard a squeak, an engine alarm and the lever became useless. max speed up to 7 kn.
I turned it off and nothing has changed.
I turned off again ant the problem was canceled, it was possible to sail.
However, every time after relapse, the problem appeared. The temperature jumps towards 100 degrees Celsius and the water pressure drops below 10 kPa.
One day I could siled without faults
Currently, the problem arises when swimming straight ahead.
After a few minutes of swimming, the temperature jumps to 100 ° C and the water pressure drops below 10 kPa.
The holes that suck the water are clean. Nothing wrapped around the bolt.
In my opinion, there is a problem with water intake for cooling. Perhaps the elements are salted by the waters of the Adriatic Sea (although the yacht was sailing normally for one day, no faults). The second one may be a defective Implerer. Pipes at the zip line are clean, undamaged.
Please guide me to the problem, where to check defects.
Currently, the yacht on the land
