115HP 2-Stroke 4CYL Mercury ... Which impeller kit?

[ClevelandBoater]

I am also having trouble realizing what pump/Impeller is for my year and model Mercury Outboard.
It's a 1990 115 HP 2-stoke 4cylinder outboard. The serial number is oc234476.

I am looking around and I can't distinguish between the 18-3214 or the 18-3214d. Is there a difference?
Seems like a lot of these motors used the same style impeller and water pump housing.

I have the manual...and it also doesn't include the correct part number for the impeller or a replacement kit.

Any help would be greatly appreciated.

Chad.


Is this a good buy?
18-3214

Or is the 18-3214D what I need?
18-3214D

I would buy the 18-3214 for a Merc as the other is listed for a Honda motor in its description. JMO
