I am purchasing a new boat with 3 HPDI Yamaha 250's. They have (each) a 5 gallon tank for the oil. The fuel tank is 390 gallons. What can I expect in oil usage? Can the 15 oil gallon tanks be enough for the 390 gallons of gas or will I need to fill the oil tanks many times?
SWT if all the updates are done it should be ok. however always carry 10 gallons or so with you. another tip. pay the dealershipto do the engine breakin. its very critical on that engine and in the event of an incedent the first thing yamaha wants is a computer download. it records all the information concerning max RPM and the past 13 min or so of engine history. if you decide to break it in yourself follow the procedure closely. you would not believe how many we get that show 10 hours below 1000 RPM and 1/2 hour above 5000 with 12 hours total and a melted piston. Idle hours dont count for breakin.
no tech questions by PM, they wont get answered.
you have to be trusted by the people that you lie to .
