...change the oil? its on a 200 hp.? I recently bought a used 1996 200 hp Mercury motor. I wanted to change the oil in the lower unit. I noticed that there was only a vent screw. and no screw in the bottom. every Mercury I ever seen had 2 screws, and you filled the unit from the bottom. I'm not sure what the deal is. is this unit different? maybe someone filled the bottom hole in and painted over it for some reason. the gear case works ok but I don't know how to put new oil in. HELP
