Re: Mercury Model and Year ID

I understand about not wanting to buy a new one, my post was just to demonstrate that part number are often superseded and in some cases the new one will fit in older motors as direct fit, or may require a different water pump as is the case with the 69 and earlier 20hp’s. So often it is hard to tell what year your part is unless you can find casting numbers on the housing and peruse the parts list to see where it fell in the production runs.

Marinengine.com has good lists to search through, as well as Crowley and others.
