| If you have a fairly new 40 hp Mercury motor that is run no more than 15 hours a year, do you need to winterize it every year? | |

Location: Athens, Ohio | Yep, also check the water impeller, since it can dry out and crack the rubber with so little use. m | |

| definitely winterize it...especially if its not used often....
Impellers should also be replaced every other year or so... | |
