Well pretty sure Ive been taken advantage of by trusting someone to be telling the truth but i noticed that when i put the trim up that i have a small amount of gear oil coming out of where the water intake is at the bottom of the lower unit.(where you put the earmuffs on when running motor in drivway. Im thinking seal kit and how difficult is this to replace? I do have some experience working on vehicles whether its my snowmobile car truck ect.
