Unless you suspect it's clogged, it's not worth the effort to change it - which requires loosening the starboard (drivers) side Cat and risking the V-band exhaust gasket.
Both good to know. I took the boat out last night and it ran just fine. I could not tell a difference at all. Fuel filter was next on my list….
