Mercury 200 EFI, am I hitting a rev limiter?

And yes, spin off fuel filter was changed for sure. I'd have to have a pro check fuel rail pressure. Will add that to the list.

JOE54...are you suggesting removing the timing advance module & idle stabilizer permanently?

yes sir

[bbarthelt]

Forgive the followup, i'm a total noob at this stuff. Would love to understand why remove them? Are they retarding the engine? and is it PC to say "retarding" if you're referring to an engine? :-p

The idle stabilizer is known to fail and the motor doesnt need it to function properly. It’s better to remove it and verify timing afterwards.
