have 1994 johnson 40hp. bot a complete water pump kit. going by a sealoc manual says to use adhesive sealant on the o-ring, driveshaft o-ring,housing grommet, sealing compound on gasket, and the four mounting bolts. guy behind counter at gone fishing marine says no sealants needed. if needed what adhesive sealant, sealing compound should i use? i'm presuming thread sealer,(not the permanent type) for the bolts. maybe marine silicone ffor the others?

Go by what the manual says and not what the guy behind the counter says.

Yep go by the manual, i always coat the bolts for example, no questions asked.
I use a permatex gasket maker compound normally, its called permatex aviation form a gasket. You can probably use many gasket selaers so long as they are oil/water resistant. I dont use the permatex gasket one which hardens, i think its called either permatex one or two ,it doesnt seem to adhere as well underwater i find

I put a touch of grease on the driveshaft splines up the top. Just a touch and nothing really on the top. Careful on that as too much can cause problem
