350 Marine Power Engines Oil Sheen From Exhaust

[Fred B]

Have oil sheen from exhaust every time i start up. Check Oil in both engines losing oil! No oil in Heat Exchanger. Engines run ok. Help!!

Welcome
The sheen could be oil or fuel

Check the power steering pump, might be the cooler

If power steering is good then suggest pulling some plugs and see what they look like and are any of them wet

 

[Fred B]

Yes we checked plugs normal carbon build up,

I think I'd be inclined to pressure test the engine oil cooler with no other data...
