Outboard Assembly Sealants (powerhead)

Forums:

Outboard engine assembly requires a number of sealants, gasket makers, oils, grease, and loctite. This assembly diagram, for most all Mercury Black Max 2.0, 2.4, and 2.5 Liters, shows where to use which products and sealants.

Since many two-stroke outboards, including OMC (Johnson, Evinrude), Mariner, Yamaha, Suzuki, Honda, Tohatsu, etc., are similar, I have have found this reference to be helpful across engine brands. Download free: Outboard Assembly Sealants Diagram.
