Outboard is on stand. How do I start it?

[ruiz2728]

I am having problems with my 2001 Yamaha 24hp 4-stroke so I brought it home and placed it on a stand. I didn't bring the remote control box with me because I didn't have time to do that. How can I attempt to start it without the control box and key? On the boat there is a black cable that is attached to the negative side of the battery along with the main negative cable. If it helps I can post pics and videos upon request.

you should be able to start it with the rope that came in the engine tool kit.

First off, thanks for the manual. I though of doing that but it says to have the key turned to the on position. I can't do that because I didnt bring the remote control box with me just the outboard, battery, and fuel filter water seperator.

I replied to this in your other post, but this throws a slightly different slant on it.

I assume you are trying to test the starter - for that, see the other thread.



Your biggest problem might not be starting it, but stopping it!

At a high level, when you turn the key to "off" it not only kills the ignition power, but also electrically does the same thing as the deadman. (Two terminals of the key are wired in parallel with the deadman switch).


What exactly are you trying to test? I thought it was your starter motor, but now I'm not so sure?

It turns out that the starter is fine the cause was just rusty terminals. But the outboard still doesn't start so i brought it to my place to be able to work on it throughout the week an not just a few hours in the weekend. I didn't bring the remote control box with the throttle, shifter, and ignition switch because i did not want to disassemble all of that. Now my only dilemma is test starting it while its on the stand.

Ok, I read form your other thereas that it was the starter motor wasn't playing!

I am guessing this engine has fairly standard electrical connections. Now, this is a high level guess, but as a 25 it will likely be configured for both tiller & remote operation. Can you borrow a control box from someone? - if not does it have a tiller as well as the remote connections? In which case it's a pull start job & put your deadman on the engine switch.

The first thing to do is google "Yamaha wiring colours". Thankfully they have been pretty consistent over the years. - then at least you know what you are chasing.

It may be something as daft as your ignition switch has developed a leak & is corroded internally - it should short the deadman when "off" - if it's not going open circuit due to a dead switch...... (and by the sounds of things your starter wasn't entirely helathy due to corrosion, so probably is the contrrol box - it's worth checking all the bullet connectors and the non IP rated microswitch in there too - those 703s are less than watertight!).

(Just don't take the side panel off when it's attached to the console unless you know whatps in there - don't ask me how I know not to do that again! - it makes an intreresting 3D jigsaw....

3d jigsaw.....

Finally the yami is running again! It turns out is was 3 problems that were keeping her from running. The first was the rotted fuel filter water separator that kept leaking causing pressure to be lost in the fuel system. The second were those wires that come out of the spark plug regulator that were corroded and weren't allowing the spark plugs to fire. And the third was a clogged disgusting carburetor. I changed the oil and now it's purring again. Thanks 9d280 for your help!

cool

It's amzing how little it takes to upset an outboard!
