    Motor has been sitting for 3 yrs now what?

    I have a 2007 mercury four stroke 25 hp outboard that has been sitting for a few years. I am not familiar with these motors at all. Where should I start for routine maintenance. I'm afraid to attempt to start it before I get fresh gas in there and change the oil. What else should I do? Thank you for the help!!!

    I'd change the impellor as well and lower unit fluid.

    Thank you. Let me know if there is anything else. Never had a four stroke before.
