so 1988 mercury 90 hp 3 cylinder i dont know much history on this engine so i first got it running. had water in fuel
. today installed a new water pump thermostat and poppet spring. the pump plate and cover were in really good shape so i did not replace the bottom plate or the top i did install a new impeller and tube seal. I started motor and i have water right away from the tell tale and seems to be pumping and plenty of water at hose. At the lower unit shift shaft i am getting water pumping out here and the hole directly behind it . I watched a couple of vids on youtube and couldnt really tell if this is normal not does the manual say anything.
