| What would you consider a lot of hours on a motor? I was recently told my motor was "tired" and I should consider replacement because it had 450+ hours on it. |

Location: Eastern Ontario | I know of commercial and guide owned Yamaha's that have thousands of hours. If motors are looked after they last a long long time. I have a 1950's 3 HP that i use on portage lakes every once in a while. I bet money that it starts within 3 pulls. Tons of hours on it not pretty but worth it's space in a shed
I have friends that put 500 hours a year on a kicker

Location: north central wisconsin | Alot of hours is relative. There are motors built 40 years ago, being run every day of the season, and still hauling the mail. I know I'm over 5,000 hours on my 1984 Yamaha 40 HP, and likely much more, but the meter died a long time ago. Likely a smaller motor than you're dealing with, but why would 450 hours be considered a time to repower unilaterally? I have more hours than that on my 2007 90 4 stroke, and it seems like it's just broke in. |

| What's your compression? If it's tired, it will be low. |

| Motor is a 135 Mariner and is a '99. Compression diagnostic was in normal ranges according to service techs who dealt directly with Merc techs to try and resolve my issue. I have a separate thread on Rough Idle about the motor issues, so I was really hoping to target feedback on hours with this thread. |

| Well...if it's in "normal" comp. range, It can't be " tired". 450hrs. Is not a huge amount of run time. Sounds like your mechanics are " tired". outboards "should" get 1500 hours before needing any kind of major repair. motors can go well beyond 1500 if kept well.
