Hey All, I picked up this old Elgin 7.5. When I went to replace gear lube this thick grease came out(I had to use compressed air)and a little water. Is this supposed to be there? I replaced it with 90w and it seems to leak a little (whitish globules in the water behind the boat.) This engine had sat for about 30 years, could the lube have solidified? Is there a special grease that was used for these? I don't want to damage anything,parts are hard to find. Any info would be greatly appreciated. Thank you
