Outdrive trim switch
 

I was playing around with the boat while on the trailer, checking the throttle play/movement (single quicksilver 300 model).

Afterwards I noticed that the outdrive will not go up or down anymore? The trailer mode still goes up but not the up/down switch?

What gives? Did I pop a fuse or did something give/or gotten disconnected? :(

Please advise.

It sounds like your trim limit switch may be bad or out of calibration if you drive is equipped with one.. :) jamie

Re: Outdrive trim switch
 

I guess the first question is do you normaly have to have the key on in order for the drive to trim? Second is were you in the bilge around the motor or trim pump cleaning or working? Check the plugs at the trim pump and make sure your battery switch is in the right position.

Just a few things to check.

Jamie,

How would you diagnose/test the trim limit switch to see if it has gone bad? Buy a new one and try it?

Actually, I was trying to see and mark my trim gauge where the outrdrive was in line with the boats bottom. It seemed different than before at the first sea trial.

John,

I tried the key and the battery was switched on. I did grease the power hatch ram grease nipple, so maybe I did knock something loose by the trim pump...I'll check it later.

Is the trailer mode on a seperate connection?

Thanks for the input.

The trailer switch bypasses the trim switch. So yes it is kind of on a seperate circuit. You can juper the wire from the trim pump's leads to the limit switch. In other words bypass or close the circuit for the limit switch. If it works it's out of calibration or bad. If it does'nt work you have annother problem.. Jamie / Lakeside :)

OK,

Where is the limit switch and which of the trim pump wires do I jumper wire to the limit switch?

Thanks,

Jamal

Ok since no one else is replying. Here is what I would do and it happens to me a couple times a year.
Take the trim limit sender unit apart. As I remeber it is the one on the port side. There are 4 philp head screws. Once you take it apart you will see how it works. Simple. Notice the position of the sensors when you remove it. Are they touching? If not, that is why it is not working. Just reposition them and readjust.
This is a 10 minute project.
When my goes out of adjustment I just use the trailer switch. I know when its trimmed to high and never use the gauge anyway.
Now if the wife was driving its a different story. :eek:

1BIGJIM,

Thanks, now I know where the trim limit sender is :D

Is that how you adjust the trim gauge with? I thought the trim gauge was out of wack at the sea trial.

Unfortunately, I will not have a chance to check this out until Sunday :(

Re: Outdrive trim switch
 

That one is for the gauge. Just losen the two screws and move it and watch the gauge.
The port side is for the trim limit so you don't over trim.
Ya da...

Re: Outdrive trim switch
 

Have you ever checked your hinge pin? My buddies boat trim switch would act up twice a yr. Every time his pin has loosened up, which changes the position of the pivoting contact switch. The contact itself can't get out of adjustment with the way it is located with the 12pt plug. The outer housing can rotate a bit, but only the amount of the slots. Enought to get out of adjustment. Not that I've seen those PITA screws loosen up by themselves. My point is if it is getting out of adj. often, there is a cause.

Re: Outdrive trim switch
 

OK,

I just got back from my business trip and I made the following progress:

Picure 1 is the trim limit switch with the cover removed....looks like the contact points are a bit off. All screws where screwed on tight.

I loosend up the two bigger screws and rotated the assembly until they touched... now the up trim works along with the trailer switch...the trim down still does not work and there is no more adjustment left on the assembly :(

Can anyone make sense of this and/or does anyone see anything wrong in the attached pictures?

Any advise is appreciated... my boat slip is awaiting :drink:

Thanks,

Jamal

Re: Outdrive trim switch
 

The limit switch has no impact on the trim-down function. It sounds like your whole unit needs some attention.

Check the limit switch with an Ohmmeter. There will be two black leads conning from the outdrive to two watertight conections near the trimpump, where they connect to a purple and pur/wht lead. Seperate the watertight connections and check the limit switch (black leads) for continuity. You can also use a piece of wire to substitute for the limit switch to check the operation of the trim up by connnecting the two purple wires together and operating the trim switch.

As for trim down you need to check for a problem with operation of the trim-down relay on the trim pump bracket. It's the bottom relay and the green wire.

As for the trim limit switch, remove the copper center contact with the one screw and use an electronics cleaner spray in the grove. Clean the copper contact wiper also until bright.

Yes, how do you get it down?

It turns out to be the throttle control trim switch after all :( :mad: :drink:
