Hello all, Just purchased my first Mercury, I have always been an OMC guy so I have a question regarding this Merc. It’s a 1968 9.8hp serial# 2510518. I have a cracked cover on the fuel pump and the replacement pump part number is 89977A1 according to marineengine.com. My concern is it looks nothing like the pump I have now and the pictures aren’t really detailed to see if it will work. Looking for some insite or advice.Thanks Dave
