Can a lower unit from a 1977 Mercury 140HP inline 6 switch out for my 1982 Mercury 90HP inline 6 ? I know alot of these are interchangeable but could use some advice from someone who knows. Thanks, Dennis
try to cross reference for your by checking lower end part matches...<br /><br />But need Model/Serial number as they do differ between these units... I will help if I can but can't guarrantee anything.
