grease and lube for mercruiser

hey guys just realized that my grease gun has run dry and they don't sell the old grease my old man has used for years! just curious what you guys use in your grease gun? is there a type of grease that I can use for the gimbal bearing as well as engine splines and couplers? don't mind if I have to buy 2 different types just easier to do it all with one!?! also im looking for bulk bottles of gear lubricant in 5 litres or so and just wondering if anyone knows where to get them pref NOR but will do what I have to. am running a 6.2 merc with bravo 3 leg. cheers guys
