When I run my Mercury 40hp EFI 4-stroke -02 at high speed, either at sea or at high idle speed, I get this alarm sound. I have a new impeller and a good tell-tale with cold water.
Do you have any idea what this alarm sound (https://youtu.be/kKA4KW79c04) could mean?
I need to replace #34 in this diagram, the 45 degree elbow fitting: 1771.png
What would you remove to be able to replace the fitting, I guess removing the lower cowl is a good idea, but how do I do that?
An elbow fitting for the water hose going to the fuel cooler has broken, #34 on the diagram: http://cdn.boats.net/diagram/Merc/COMMON//1771.png
Can I bypass the fuel cooler (temporarly) and connect the hose going to the cooler to the hose going from the cooler, so I can get back home, or will...
