Hi,<br />I just bought a F150 yamaha..... I did some home work on them and found that they are a good reliable motor (even though they are only on the 2nd year) my ? is....is there a tool to pump the oil out without haulling the boat out... and how often to other owners like to do it? compared to a complete change including total drain off and filter change.....Also which recor filter would you recomend....appropriate Gallon flow and all...thank you
