2010 250 Etec service question

[Eric521]

Taking my boat back to dealer in a few weeks for yearly service...lower unit oil change etc. Just wondering if anything else needs to be done besides the basic. Going to have lower unit oil changed, new spark plugs, fuel filter change. Anything else that should be looked at?? Whats the life expectancy of the impeller? Thanks

They should also check for the latest MAPs on the EMM, on the average if used in good water the impeller should last 3 years or 300 hours which ever comes first. In shallow sandy water it should be replaced more frequently.
