| I have a balky trim which is getting worse, making a lot of extra noise and
sometimes not responding, and then responding slowly to repeated demands.
Is this more likely
oil leak
o ring problem
trim motor problem?
This worked well on my August trip to WI, and has just started causing problem/making noise the last two trips. | |

Could be a number of things, wiring, brushes, o ring problem, needs new fluid. I just went thru this same thing a month ago and my motor was bad and I replaced it. My buddy was having issues similar to yours, he replaced the fluid and his motor works great. | |

Location: Eagan, MN | My guess would be water got into the electric motor that runs the pump. I had it happen to a not very old Merc. Ended up a missing Oring was the culprit.
If you catch it early enough draining the water and cleaning up the brushes and motor could solve your problem. Of course you'll have to resolve the problem of how water got in too. | |

| Here is a review of this problem and what has worked to fix it. Thanks to those that responded. Lots of times, somebody has already been through these issues.
My trim motor had been working fine over a two year period, including a trip to MN/WI this summer where I fished about 17 days straight without problems. Since then over a period of 3-4 1 day trips, my trim motor has started sounding rough at times, not raising or lowering the motor initially at times or taking extra time to do it while sounding rough. This rough sound was not constant, it might start sounding rough and then sound like the normal trim motor sound and raise or lower the motor apace once it got started. So it wasn't a complete lack of response but slowly degrading toward what I felt would be that point.
I went to the local boat shop, South East Marine in Corbin, KY, and talked to the parts guy Bob, and their two motor guys, and got the advice that the first thing to try, and most likely by the sound was that it might be getting low on oil, and also what to do, fill, and raise and lower motor a few times, to bleed air if needed. Got a small container of trim oil/hydraulic steering oil for $5.40 something and added maybe 3 total ounces of oil in the fill/check port(plastic). I double checked the position with another phone call to the guys, since this port is quite low on the apparatus, and would not logically seem the choice spot to add oil. I was able to get the motor raised all the way up(neccessary, since system under pressure if motor is not all the way up) and added this tidbit of oil to the hydraulic system, simply adding a little until it drooled back out on the floor, and screwed in the plastic plug again. Response was nearly immediate and any roughness soon was resolved into the normal whine of this hydraulic system, and response was back to normal.
I would like to stress how LITTLE oil this took to change system from barely functional to fully functional, I mean we are talking 6 tablespoons of oil volume total added, but it sure resolved the problem. And missing those 6 tablespoons sure was affecting the performance of the system prior to the replacement.
A big plug to SE Marine in Corbin KY. They have always been real helpful with my boating problems, even though only 1 of my last 3 boats were purchased there. | |
