Hey everyone..I have an 2008 mercury optimax 150 that is on its third season. Every fall i drain all the water,change my lower unit oil and put 1 oz oil in each spark plug hole (per manufacturer suggestion). Thats my motor winterization..Just wondering if there is anything special that I need to do for a three yr maintanence this fall other than what I'm doing. I have approximately 150 hrs on my motor and love it.

Thanks a bunch
Jason

you need to change the impeller.Should be done every 2yrs.Rebuild the waterpump every other impeller change or every 4yrs.Impellers cost@$20.00 and are not hard to do if you wish.Just look it up on here.other than that,barring any problems,just follow you manual for maintenance.

You also need to be running a additive such as Merc Quickleen,Yammy Ring Free or BRP carbon guard every other tank.
