Go to Wal-Mart, look in the boating section and buy a pump thats used to fill the lower unit on boat engines. It will screw right onto the gear lube bottle and pump it with no mess or waste. Depending on the location of your fill hole you may need a small piece of plastic hose to attach to the end of the pump. Also available at West Marine and Boaters World. Cost is around 7-$10.00. Better yet, if one of your friends owns a boat borrow theirs.
