    Exhaust Manifold & Riser Replacement

    I see many people replacing their exhaust manifolds and risers. What is the reason for this and how do you know when it's time to do so? I have a 3.7 4 cylinder so it obviously only has one of each. Thanks for the advice.

    Winterizing 2008 4.3L

    I recently purchased a 1987 Mariner outboard 3 cylinder oil injected. I got it running in a garbage can and it shifts very hard. The boat has been sitting for a couple of years. Do you think if I run it awhile will this loosen up? I also can't find an exploded view of this particular gear...
