    Default Yamaha Oil Level on Dip Stick???

    When I picked up my 60HP yamaha the oil in the engine was up to the top mark on the dip stick. It stayed that way for 21 hours of running time. I had the 20 hour check-up today and when I got home I checked the oil. They only filled the engine to half way between the two marks on the dip stick. I called the mechanic and he said that yamaha only wanted the oil to be half to two thirds on the marks, and NOT at the top mark. My first question was why was it that way when I got it? No real answer. The owners manual says to fill the oil so that is between the marks with no reference to where. So technically the current level would be acceptable according to the manual, but in my thinking it would be better to have the most oil allowed and have it up to the top mark. However, has anyone ever heard of this before? Where on the dip stick is your oil level?

    Thank you;

    To much oil can be bad for an engine and so can to little. I try to keep mine in my truck, cars, and boats all in between the to marks. With the dip stick you are simply measuring (I think) the amount of oil in the oil bath so there is a little room to go either way and that is why its a range and not an exact amount.

    Ric....my 4-stroke recommends the same as yours. I prefer to have it on the high side of half-way because when it is running some of it is in the oil filter, dropping the oil level in the sump a little...not much since the filter is horizontal. With the engine sitting dead level, if I put in the recommended 2.11 quarts, the level will actually be above the full mark so I stop at 2.0 which leaves it about 2/3 of the way up between the marks.

    I bought mine locally and the Mechanic that did the walk thru with me told me to keep it in the middle. He is their "go to" Mechanic BTW, from my observations.

    I changed oil and filter back in the spring, and filled it to spec which hit the stick a little above the half mark. They tell me that is where it should be.
