Hi there, I'm a new member from Queensland and hope you can help me with my cooling problem. I have a Riviera 3000 Offshore qith twin TAMD41Ps. I have just fitted a new turbocharger to my port engine as I was unable to get the engine over 2000rpm. New turbo has fixed the problem but I am now getting steam coming out from the exhaust outlet and also the coolant level in the engine's header tank drops about 10 - 15mm after a 2 hour run at around 3000rpm. Any ideas as to why the steam and where my coolant leak may be.
