  • Compatible lowers for my 1984 Mercury 75HP? Serial: 6558246

    I'm wondering if there is some sort of cross reference sheet or web site for Merc parts. My 1984 75hp Merc - Serial: 6558246 says the lower should be 7333A25 but the one I just pulled of was part number: 5166-7332.
    BTW, I'm getting part numbers from the EzPartsWeb site: https://public-mercurymarine.sysonline.com
    Is there a better site???
    Thanks in advance guys!

      Thanks for the reply faztbullet! I picked up an 1980's 80hp motor yesterday that I THINK will work just fine. It looks IDENTICAL on the outside, but I know... the proof is in the pudding! I plan to try it later today.
      BTW, did you mean to say: "horsepowers are 65/75/80/85?" I just need clarification.
      THANK YOU!
