First time for me to change water pump in a Mercury. Question is, once I drop the lower unit, remove the old water pump and impeller and put the new on and ready to slide the lower unit back on to the mid section, is it required to put a bead of silicone around the top of the lower unit when putting it back together? Also, is there anything else that I need to look out for when putting it back together?
I do not have the serial number with me at this time to put in here. Hoping that the question s generic enough that it isn't needed.
Thanks
