25 HP 4 stroke oil change?

[Kenneth Brown]

Father in law recieved a small pontoon boat with this motor whenever he bought his lakehouse. I haven't looked at it at all yet but he wants to change the oil. Any ideas or pointers that I should know? What is the reccomended oil to use and how much? Does iboats offer the filter?

yamaha reccomends their 4 stroke approved oil we used to use 10-30 in them, the SAE grade requirements and capacity is on a tag on the flywheel cover, dont know if anyone offers the filter yet other than merc or yammy.<br /> if the ign module says motorola its a merc with a silver blue paint job.
