Off engine fuel filter for Verado 200hp

Has anyone added an off engine fuel filter to a Verado engine? Can you place one inline with the current filtration system? What Micron size should be used? I've thought about adding a 60gph, 2 micron Racor filter in the fuel line. Too much restriction or will this work without bypassing/removing the existing on engine "red" filter? The new large V rods have an off engine filter and no "red" filter as I observed on a 27' pontoon with 2 400's!

Use a boat mounted water separating filter. You can get the 10 micron. Another 2 micron that close to the source is asking for trouble.

There is a kit from Mercury to do this. It eliminates the on board filter and adds a much bigger racor style filter. It has the correct wiring to have water separating monitoring.
Merc really does not advise running 2 filters.
