This is an amateur video, published in good faith but with no guarantees as to accuracy or safety. Engine maintenance can be an inherently dangerous activity, so you need to carefully research the risks, consulting multiple sources of any critical information. Be sure to consult the dealers manual for official maintenance policies -- this is available as a free pdf download for most of these Yanmar engines. Any misadventure you encounter if you decide to take the risk of repairing your own engine is your responsibility.
