The YAMAHA system is nothing like the MERC system. It uses a remote main tank, then a small engine mounted tank. The remote tank uses a small electric pump to transfer oil up to the engine mounted tank and is triggerred via a float switch in the engine mounted tank. If the pump stays running it will run over and pour oil out.
