My Mariner serial # is 0B396769, I believe its an 1989. And I need to know how to cross reference to the Mercs. I have also checked the (what year and model my outboard is thread) and no luck. What are my exact specs for my Mariner? Also will a 40 or 50 HP Mariner lower unit work? Thanks again for all the great info on this site!"

"Yes, it's an 89 model and it's a Mercury/Mariner, so just a Merc painted grey with different stickers.

In that vintage (upto and including the 1994 model year for sure) the 50, 55 and 60 horse models shared many parts, including the lower unit, so you have a pretty good group to scavenge from - particulary the 50's which is one of Merc's best selling motors...."
