You don't need those branded items. For the Gear lube, go to Wallyworld and pick up a bottle of SuperTech Marine Gear lube. If you are worried about not having the name brand, pick up a bottle of Pennzoil instead, but it's all the same stuff, held to the same standards. Your merely buying the name.
On the grease, you'll be just fine with any old marine grease, also available at Wallyworld. Any marine grease is going to hold up fine, even in saltwater. I keep one grease gun with marine grease (not brand specific, just whatever is on sale), that I use for all my outboard grease zircs, prop shafts, and trailer wheel bearings. In a bind, standard (non marine) bearing grease will do you fine for all of the above. Currently, I'm keeping MAG-1 marine grease, as a couple years back, when an Auto parts store was moving, and placed everything in the store at half off or lower, I bought them out. Have used up the number of tubes of Pennzoil grease I bought at that same time.
If you don't already, you'll be just fine using Supertech two stroke oil too. 'Bout the cheapest around, except when Pennzoil is on sale, and again, meets the TCW3 rating, so it is a-okay for use in your motor. It's pretty much all I use.
