| Post subject: | Thompson trim unit ? |
Can anybody tell me what is the average life span of a Thompson trim unit? I bought my mb sd used in February and I was told the trim would probably go out soon and it did so I changed it saturday. I never thought of asking how often he had to change it. I'm just trying to get an idea if any of y'all can help, thanks. |

Usually over 100 hours. The seal that the shaft slides through is the culprit on the Thompsons. Keep some grease rubbed on the shaft/seal and youll squeeze a few more hours |

Good to know on the grease, my motor had 105 hrs when I changed it so it's probably the first time, I'm guessing, thanks a lot. |

Quack look around on the mb Site and there's a guy that told how he repaired his. It might save you some cash next time around. |

Thanks med, I'll check it out, I know when I took my old one off the seal was dry rotted pretty bad, if I can make it last longer or fix it that would be nice. |

The trick to keeping them going is to check the seal often. If it looks damaged or degraded pull the unit off and repalce the seal. Their only $8.00-$10.00 and a piece of cake to change. If the seal gets damaged the unit will get wet and take a shit. I am thinking I will change mine out once a year. Cheap insurance to make them last. |
