I have just purchased a boat with twin 2002 150 EFI's. (400 hours all fresh water ) both water pressure guages read 2-3 PSI at idle, and dont get much above 5-7 psi at 4000 RPM. I changed both impellers with complete kits with no change. A long idle will cause an alarm that im assuming is overheat warning as it goes away with a throttle bump. At 1000 RPM it will idle forever with no issues.
The tell tale stream does get hot, but im not sure what that temp should be.
These is my first boat with outboards. Im used to BBC so any help/advice would be appreciated.
