I usually just coat both sides of the new base gasket with grease…  Can’t hurt to use sealer though, but it should be relatively light/thin, no need to make a mess and plug up passages

I used to use gasket sealer, but after destroying countless base gaskets that were installed with gasket sealer, I now use just grease. By using grease, you will most likely be able to reuse the gasket next time you remove the powerhead. Don’t use anything harder than aluminum to clean the mating surfaces to avoid scoring them.
