Good evening, I want to know how to change steering hydraulic oil with a teleflex seastar dual outboard system? I won the 1993 27' fountain sportfish on e-bay. It has 2 200efi saltwater mercurys with 20 hours on them. Can I just bleed from the motor cylinders and keep adding fresh oil until I see fresh oil? How do I get the air out of the lines? Is it like a car, the furtherest from the reservoir first?<br />John
