Hi, i am replacing the waterpump of my outboard (1988 merc 115). Before replacing the lower unit back onto the engine it is common practice to place a bead of marine silicone between the water pump housing and the exhaust port.
Should i let the silicone dry first before replacing the lower unit? I have seen it done both ways (dry and wet) but i am concerned about which way is correct. It makes sense to let it dry first, but most videos i watch they leave it wet.
Does anyone know the best method?
Thanks
