"Having a bit of a problem wit
"Having a bit of a problem with a Volvo Penta MD 6A engine, installed in my yacht.
The engine will idle ok, up to 3200rpm, exhaust emissions are clear / normal.
When in gear and under load, the engine reaches a maximum 16oo rpm, 3 knots, with deposits of oil exiting from the exhaust.
Normal performance of the engine would comfortably be 3000 rpm giving 6 knots.
Fuel & filter, air filter, oil & filter, injectors, cylinder head gasket have all been replaced. The valves have also been re-ground and engine re-assembled.
The problem still persists. Engine is 35yrs old and has been regularly maintained over the years.
Has anyone experienced these symptoms with their engines – any advice would be appreciated."
