2 stroke Merc 150 routine maintenance
 

I'm curious of who would get the nod on boat preventive maintenance. I have an older Mercury 150 black max that runs great and I'd love to keep it that way. I have zero experience and would love some input. So far it has been a great motor and I simply would like to ensure I do my part in taking great care of it this off season.

when i ran my 2 stroke yammi, i would change plugs every year. fuel filter, lower unit oil. changed impeller every 2 years. Think thats all. ran it from 2004 until this year when i sold it to upgrade to a bigger boat. Boat was still running great when i sold.
