    Other than reading and following the owners manual instructions can you give me any advice as to the proceedures, break-in oil type, etc. that can help me insure a good long life for my new Yamaha?

    Thanks in advance.

    Qwners manual says it all.
    One bit of advice...invest in a OEM shop manual,
    if you plan to do your own repairs over the years.

    I have 4 gallons of Blendzall Green Label oil. Can I use it in this outboard?

    #460 "Green Label" 2-Cycle Racing Castor


        The "original", formulated from the cleanest-burning castor. Blends with gasoline or methanol to provide sustained performance at high internal temperatures and RPMS. Contains a rust inhibitor and seal preservative. Seperation may occur with some gasoline in temperatures below 50 degrees Farenheit. Add 2 oz. #490 Power Booster to one gal. gasoline to eliminate seperation.

    Nope, not good for outboard motors that run anything but wide open throttle. (racing)

    Castor based 2-stroke is not good to run all of the time, unless u like to do top-end jobs..  I'll run it every once in a while, a little more carbon build up than synthetics, but it smells, oh so good.. ;D

    I use it in my model airplane engines....

    I bought a set of floats for one of my planes so I can fly off the water and after I crash I can go get it with my new skiff...... ;D

    I also used some CRC Di-Electric grease in the squeeze cheese can and shot a dab in the spark plug boots and all of the wire connectors one at a time.

    The wire connector boots are well made but there is no grease to protect the plated connectors. Hopefully the grease will also protect the copper wire and keep salt/water from corroding the wire(s).
