| I do mine. Not too bad a job. No special tools required, really. A second person to help lift it back is nice, but not required. Get a manual, and have at it. |

| Shep is right I would change it yourself.
I took mine in even though it pissed fine and the temp was always good. But it is a 2001 motor and I do run on some sandy lakes. So I told them to rebuild it. $137.00 +1.5hrs labor was the bill.......I was told $90 total...but they changed thier mind and said because it was a 225 Opti. An impeller is an impeller...right?
Sheesh...as someone says..
So do it yourself...I wish I had. |

Location: Superior, WI | I've worked on outboards for a lot of years and I still don't see the need to change an impeller every couple of years. Maybe if you continuously run extreemly long distances. Most impellers will last at least 7 to 10 years. |

| Ya, don't change it for 7-10 years! Guys like you are the reason people ruin there engines. Mercury outboards have two intervals for changing the impeller. A 100 hr change or a 300 hr change depending on the type of engine you have. Stick to the intervals and you should have no issues with overheating. |

| Yea,
For twenty some dollars I would change it out every 2-3years. If you have a water pressure guage, it
will tell you when you need to. |

| First motor was a Merc Keikafer 50hp, original impeller never had a problem for manya years, still ran great when I sold it! Now that thing had a lot of hours on it. Only changed one impeller in my lifetime that was on gramps 1952 Firestone that dry rotted after sittin for 20 years.
Good Luck

| I would check your owners manual. I just picked up my new 115Opti and according to the manual it should be changed after 300 hrs. There is nothing in the manual about changing it after 100hrs. |
