water pump gasket sealing and compount/adhesive options?

[cfh1177]

I’m replacing the water pump in my 1988 Evinrude 20HP (E20CRCCA). The water pump kit came yesterday and I was reading the instructions last night. Saw that I need BMCA Adhesive P/N 318535 for the impeller housing seal and BMCA Gasket Sealing Compound P/N 317201 for the gearcase surface (not supplied with the kit). Since we are talking about gasket adhesive and sealing compounds, are there alternatives that I would be able to pick up from an auto store like Advance Auto, Pep Boys or NAPA? If so, what should I use? This is the first time for me doing this.

Thanks,
Mark
