trim problem pls help
 

I can trim the drive down......but using the throttle switch to trim it up does nothing, I can use the "trailer trim switch" and it trims very slowly to a certain point. I've adjusted the trim indicaters on the drive but this made no difference.

Also when running in the water it trims down fine, but when trying to come up the trim pump sounds like its all over the place, it whirls up and starts spinning all over the place........any suggestions???

Had this happen to me not too long ago.

If the motor continues to run but it looses it's lifting ability the pickups are probably clogged. The resevoir will build up sludge at the bottom and clog the mesh socks on the ends of the pickups. Disconnect the lines and pull the pump out of the boat. Remove the resevoir and dispose of the oil. Clean the resevoir out and also clean the mesh socks.

OK I think I have the trim indicators screwed up also, gauge reads that the trim is up even though it's not.

Is taking the pump out a fairly easy job.......trying to figure out if this is something I can do.

Are there any special tools that are needed to get the pump out? I also noticed on the starboard trim adjustment that one of the wires is cut just a little, wonder if this has anything to do with it.

I'd like to tackle this job myself, can anyone tell me if it's fairly easy or ????

Was told that the 2 mesh's could be clogged, etc.....where are these?

If you look at the trim pump you will see a plastis resovoir that the oil sits in.If you reach down under this plastic tank there is a 10mm bolt that is recessed into the plastic and is screwed up into the pump itself.This is the bolt you need to remove and the tank will come down and away from the pump itself.Clean out the tank and notice if there is any sludge in it.OPnce the tank is removed you will see the two pick up screens hanging down from the pump assambly that went into the tank to suck up the oil.Clean them and then reinstall tank with new oil.Just make sure the O ring between the tank and pump goes back in when you reinstall.

You hit the nail on the head......boy was it nasty.......gunk was all in it. I cleaned out the reservoir and got it all working, comes all the way up now. The throttle switch only works going down and I have to use the trailer switch to bring the drive up.....I think this is just a faulty switch though.

This is due to your trim sender setting on the drive. You said it shows up even when the drive is down. Adjust it so it shows down when the drive is down and it will work fine. Its a protection to keep form trimming too high and damaging the U Joints.

Ok, have been trying that but I can't get it set right for some reason. I've turned it all the way in both directions but still same thing. trying just moving it slightly now till I find the right setting.....

I think I'm just going to bypass it, but not familiar with how to do this, any of you guys done it?

I know the risks.....i just won't raise it high when underway of course.

The sender could be bad or stuck inside. It could also have a short or bad wire. They are a pain to replace as the wires go through the transom assembly and plug in inside the bilge.
The sender just works on a pendulum type balancer inside that sends a signal to the guage.

Its basically already bypassed with the trailer/trim switch.

But is there a way to bypass it with the throttle switch, that'd make things a whole lot easier.

I've seen some posts about wiring it by the trim pump using a jumper , but I'm not exactly sure what to wire up???

I'm pretty sure it's a black 2 conductor wire that looks similar to a lamp cord. You can use a piggy back connector and jumper them together. (I've done this before, but it's been awhile. :p )

behind the motor there is 2 black zip wires comming through the transom for a total of 4 wires, 2 wires are for the trim sender and 2 are for the trim limit, the trim limit is the ones that let you operate from the throttle or from the trailer, the limit switches have 2 male bullet connectors on one side and 2 female on the other side, find those wires and jump them together and your trim switch should work if the sender is the problem. but at that point the system will nolonger know what positon the drive is in, so you will have to trim by feel.

is this what I should do?

also here is pump......confused as to which wires to connect together.

no to the first one, that is just a test to check the pump.
on the second one, the wires are there, but you can't see them, look behind the motor at the transom plate above the coupler, you will see 2 black exstension cord looking wires, they should be zip tied up so there out of way, find those wires and you will see the bullet connectors that i'm talking about.

No. This first one is showing how to test your solenoid. It's bypassing the solenoid and putting power directly to the trim motor.

OK so once I find the 2 black extension cord looking wires at the transom plate and the bullet connectors........then what do I do?

Sorry for the dumb questions....just want to make sure I get this right.

on one set of cords, there are a male and female bullet connector, those are for the trim sending unit gauge, on the other set of wires, there are 2 male connectors, those are for the trim limit, these are the 2 wires that you want to connect together, unplug them and the wires on the engine side need to be hooked together, that should make your trim switch on your controls work, it will bypass the trailer button and you will have full control of your trim and tilt from the shifter.

OK got it done, excellent directions.

Thanks very much for the help guys.
