Mercury Outboard pre 1997 40/55/60? Powerhead Case Parts. This powerhead case comes complete with intake, manifold and reeds. There are two sleeves, and this case will need a final sleeve as one is missing. I do not know the history on this powerhead as I acquired it through a purchase from a closing marina. I’m sure this case has a lot of good parts and can be also rebuilt. What you see in the pictures is what you will receive. This is a parts cell only, therefore, there is no warranty and or guarantee. This is an as is self with no returns excepted.
