GOOD MORNING
My boat is fitted with one YANMAR 4LHA STE 230 BHP . And with 1300 total working hours . Recently I observe coolant (fresh water) leakage perhaps from the heat exchanger.
In order to find out the possible cause of leakage I would like to ask you if the manifold flange is connected with the cylinder head
Is there any case of manifold flange crack.
If not please tell me the possible cause of leakage and if this problem occurred in these engines
Best Regards
NIKOS
