S/Y Susanne you?re too late for me.
Bavaria 36 Year 2000 Engine MD2030C
After being on the hard we launched early April. On starting the engine water was coming out the exhaust but then the sound from the exhaust became louder no water was flowing.
I fit a new impeller but water was still not flowing. On closer investigation when the pipe was removed from the inflow of the intercooler, water flowed but exhaust gases where coming back through the intercooler, so the pump could not over come the pressure.
Then I noticed there was no water in the engine cooling and I had checked this 1 hour before.
The problem was the aluminium heat exchanger body had blown a hole near the exhaust elbow and water was just running into the exhaust out of the engine. Volvo?s price for replacement £2000.00
. So had a mate to weld it up for me £60
.
Then on looking at the elbow it had total broken up on the inner sleeve, this made it easy for the back pressers to be directed up back across the heat exchange not allowing water to flow. Have now made a 316l stainless steel elbow
.
Therefore I agree with S/Y Susanne you have to keep an eye on the elbow
. I will be taking the elbow off every year when winterising just to clean and observe and would suggest some boat owners would be shocked at what they saw as these elbows are not just on Bavaria boats
