Re: How good are older Mercury outboards. chum1 said: Blue or redband I dont think makes much difference, Parts might be harder to find for the old distributer style ignition ( and there is more moving parts) vs the coil per each cyl. type ignition, but mercs are good and worth working on.

Jun 23, 2009 · Re: Mercury vs. Mariner what is better. Many models of the Mercury and Mariner are indeed the same unit with different decals.
