Bmw outdrive stuck up any ideas

[Waters reach]

I've just ordered some chest waders so I can stand on tge back of it. Its in the water you see and I don't want ti get soaking wet when I stand on it. Its going to be tricky as it is as there is a swim platform there. I will let yoj know what happens when I go down to tge marina . Thanks guys

Thanks guys for all your tips , hoping to go down to the marina this weekend so will try everything you've said, one point though about fuses, where do I find the fuse panel as I can't seem to locate it. Sorry guys I'm new to this boat and totally different to my last

My fuse was a very specific individual one bolted to the side of the engine and set in resin - app 1.5 inches sq and 1/2 inch deep - might be called a shunt but what do I know it blew, I replaced it, it was fine!

It should work, but don't start the engine with the drive up the UJ will "knuckle" out and do some damage if you run it for long. Something unique to BMW outdrives!

Glad you specified "unique to BMW outdrives". I have a Mercruiser on my skiboat and occasionally run it for a bit when negotiating a shallow spot. Would hate to trash the drive.

Hi guys
I'm at the boat today and your right there is z clicking noise coming from near the inside of the outdrive. What does it mean and what do I need to do please ?

Sounds like the relay is trying to engage the hydraulic pump to engage in the down mode. Do you also hear a whirring or similar sound that would be the motor and pump trying to send hydraulic fluid to the lifting/lowering rams?

 

[skipmac]

And have you checked the fluid level in the pump reservoir?

Right guys I have sorted out why the leg wouldn't go down. The down lead was not connected but when I connect it , it goes down with pressing the switch down (hence why it was disconnected) so I've now got the leg down which is great but what is causing it to go down without pressing the switch down

dodgy switch? if you can use a multimeter, it's going to be a 5min job to establish the fault.

also swap the two end cables on the switch and see if the problem moves to going up by its own Switch should have 3 cables one in the middle which is "feeding" the two directions. OK, may have 6 cables as well or 5, no less than 3 for sure...

First thing I would check would be the switch. Like vas said, get a meter and you can sort it out in a couple of minutes.

Well done ... I had a similar problem and took a while to find the dodgy connection.

Oh yes. Congrats to W.R. for finding the problem. Might have to connect and disconnect a wire until he finds the source of the bit about going down without using the switch but at least he's got up and down.

Sorry I wrote wrong when I went to connect the wire the pump started and the leg went down WITHOUT pressing the down side of the switch. So that's obviously why the previous owner had disconnected it. But now I don't know what's causing it to do that

Could it just be the switch?

Yes, it could. But to complicate things for you - is there a relay between the panel switch and the solenoid valve? A stuck or failed relay could be causing the problem. Less likely is a spurious power feed from somewhere, so check all wiring is neat tidy and in good condition.

One other thing, if it's going to do odd things under power make sure you keep clear of the moving parts, and you have access to the circuit breaker or master switch.

Agree. Could be the switch but on my boat there is a relay between the switch and the pump motor. When you connect the down lead to the pump do you hear a click or does the motor just start running? If no click I would suspect the relay.

Also easy to test the switch if you can get to the switch or the wiring. Leave the down lead disconnected while you do this. Get a voltmeter and set it to read resistance or continuity. Better meters will have a beep or a buzz to indicate continuity. Hook the meter up to the leads going in and out of the switch. Should read open IE infinite resistance when the switch is not pushed. When you push the switch it should show a short circuit or continuity. If you read continuity both ways then probably the switch.

I didn't hear a click but then the noise of the pump may have hidden that. Sorry im really green but what does a relay look like ? Also I will buy a new switch as I don't have a multimeter . I've attached a photo of the switch will this suffice?

I can easily make the switch fit as I have a drimmel ,brilliant little tool.

Love my Dremels. Yes plural. One on the boat and one at the house.
