Give the Mercury Marine factory in Fond du Lac, WI a call. Just order the maintenance and parts manuals for the drive. All the info is in them. They are cheap and will save you time trying to lookup part numbers. (920)929-5000

If it s a dry sump #6 then you will need a special tool (91-847468T & 91-847418) to remove the nose cone and change the filter. The gear lube is pumped in through the bottom plug, just like a Bravo, but once it reaches the top hole you need to rotate the propshaft 80 times to fill the filter cavity. It doesn't matter which direction you turn it. Afterwards, re-check the fluid level and then put the plugs back in.
