Screen Fuel Fltr 35-8M0090809

Is there a prescribed interval for when Screen Fuel Fltr 35-8M0090809 should be replaced?

[boats.net]

Every 100 hours or yearly should be cleaned or replaced.

Then why have two different certified Mercury Service Centers who have serviced the engine each year for 4 years never ever done so? Why does the Mercury 100 hour service kit not include it? It includes the inline fuel filter but not this one. It is not mentioned on the Mercury video showing how to perform the 100 hour service.

I should have added, I am not disagreeing with you. I think it should be replaced every 100 hour or annually. But to the best I can tell, service departments are not doing it, and I can find no instruction from Mercury regarding this part. In fact most people I have asked do not even know there is a filter inside the fuel injection rail.
