1998, 305 intake question

[Northportdiver]

I have a 1998 Mercruiser 5L, 305 with a mercarb carb.
What is the metal shielded flex hose that connects the intake to the stbd exaust manifold?
Someone told me that it is for very cold climates, but was NOT sure.
Can I remove it since I live in Florida?

Be careful as that tube is the hottest part found on the engine under normal conditions. It gets over 200 degrees.

Best I know about it is It's an excess fuel exhaust vent tube mostly used for the emissions control system. Merc started using it with the small block Gen 2 (GM vortec) carbureted and TBI engine models. If you can, it's best to leave it on.
