New member, first post. Great resource!
Just picked up a 1978 Merc 402 that has been sitting unused for 5 years. Submerged the lower unit in a 55 gal drum filled with water & got motor running, but no water was exiting the tell tale. Suspecting water pump problems, I pulled the lower unit & found the impeller damaged -torn & missing chunks. Also found the spring on the water pump lower body oil seal broken and other damage on the top cover so I have a full kit on order.
I was wondering if there were some other cooling system checks I should make while the lower unit is off.
Thanks for the help,
