Mercruiser Maintenance

[RatFish]

Hey all, It's been awhile. I have a 2006 Mercruiser 350 MAG, serial 0W361889. I have 265 hours on the motor and was wondering if I'm due to replace the Spark Plugs and raw water pump impeller?

Yes ............ on both counts.
If you have a Bravo outdrive, you should change the impeller every other year. Regardless of hours.

Yup, Bravo 3. The manual states "Inspect the seawater pump and replace worn components" at 300 hours. Says nothing about spark plugs.
