Hi everyone and new to forum and hope you can help. I have twin TAMD 31P's in a Blackfin 30 ft. I had recent
fuel contamination and cleaned tank,
fuel and new filters. Now one
engine runs ok and the other will accelerate to full
rpm then, quickly dies putting out black smoke and runs at 2500
rpm. If I bring that
engine back to idle and accelerate again it will run up to 3000rpm and run ok. If I exceed the 3000rpm it dies again back to 2500 rpm and black smoke. If I reduce the throttle, the black smoke goes away , but it will not go more than 2500rpm unless I go back to idle and accelerate again.
I suspect a full flow issue- I checked fuel lines for flow and new filters. I have primary Raco 500 series filter and
water separator. Any ideas please.
Boat is clean and props good. Many thanks Robk
