The time has come to change my oil in my Yanmar 2GMF 2 cylinder engine. I have purchased the new filter and a device to suck out the old oil through the dip stick. My question is how much oil does the Yanmar 2GMF hold and what weight should I use. I just purchased this boat this year and the pervious owner said that he used synthetic oil. Should I stay with this?
