Working the max 2 this weekend

[swamp donkey]

Got the new max 2 in the garage today and put it through a lot this weekend. Put the first 6 hours on it retrieving 3 deer and 2 hogs. Had to swim about 300 yard across some flooded timber to get our kills back to camp. Made the trip 8 times. Now my question being in all that water and mud how much grease should I put in the inner and outer bearings. I have already lubed the chains. also is there any thing else I should check while doing the first maintenance thanks for all the help
