| Post subject: | Need help with trim pump motor |
I recently purchased a 1992 Horizon 190 with the OMC 5.0 HO and OMC stern drive. I am in the process of making sure everything mechanically works. While on my first test outing with it, the trim stopped working. I got it to work again by smacking the trim pump. I assume that the brushes in the motor are going bad. I would like to replace the motor. My question is, can I just remove the motor or do I need to worry about the hydraulic fluid? This seems to be the only major (If you can call it major) problem on my boat. Any advice will be greatly appreciated. |

That’s it! Thanks! I have one other question though. Will removing the motor let out the hydraulic fluid? It looks like I might get away with just swapping the motor out. On a side note I am bookmarking that site. I love the parts catalog. |

Not sure about the fluid loss. The only one I've delt with is the Volvo pump which has the motor on top of the reservior. |

Well, I pulled the trim pump off. It really wasn’t that hard of a job. I unplugged the battery. Then I unbolted it from the back of the boat and removed the various wires making sure to mark where they went. I did not disconnect the hydraulic lines. I then unscrewed the 3 screws that hold the pump to the reservoir. I then began to carefully remove the motor. This is when I found out for sure that removing the pump motor will let hydraulic fluid out. I was being careful so I only lost a little. I quickly flipped the motor and reservoir around so that the reservoir was underneath the motor. I then removed the motor completely. Instead of buying a new motor, I took a stab at fixing the old one. I found 3 screws held it together. I opened the motor and found the problem. One of the springs the held the brushes against the spindle was rusted and stuck. I took the spring out and cleaned the unit and spring. I reassembled the motor and pump assembly and tried it out. It works! Now all I need to do is make sure it has the proper amount of hydraulic fluid. I have not spent the time to figure out where to fill it yet. That will be a weekend project. It does move the stern trim up and down and seems to be fine. But I want to make sure. Next time I will take a few photos so everyone can see what I am talking about. |

Have the drive trimmed all the way down when you fill and check the level. |
