well here a good one can anyone find me the part number for water pump kit with housing(top n bottom) for 1965 mercury 350(35hp) serial# 1900651 I have been all over the internet and can't find it anywhere
See under GEAR HOUSING ASSEMBLY, COMPLETE (PAGE 1), item 32. I would call to ask if it has everything you are looking for. Other than that, order the individual parts.
