Hi,<br /><br />I am new to boating and just purchased a new boat with a mecrusier I/O 220 alpha 1 sterndrive. I have noticed alot of posts concerning engine problems. I was wondering what I could do to prevent potential problems besides the recommended maintenance by the manufacturer. How often do you change the oil? Filters? etc. Is there something that I can do now that will help me in the future. Thank you insight and patience...Thom
