Electric outboard repair

Post by kristian » Wed Jan 09 2019 22:19

Has anyone got any experience of repairing electric outboards. I’ve got a excursion 62lb thurst engine and it’s just suddenly stopped working.

The power lights are on but there’s no one home.
I’ve taken the top part to bits and the speed controller feels a bit crunchy, especially on 1-2 reverse settings. Is there a way of testing that this could be the problem before I replace the part?

Reading up online common problems are this or the brushes. I don’t know quite how to access and check these though.

Most electric outboards are relatively simple. Power to a speed control, which is a switch and a few resistors, then the actual motor itself. My minn-kota played up recently and it was the switch (speed controller). You should be able to see if there is power coming out of the motor side of the switch for a start. I'm sure there must be youtube of how to access the motor, and brushes are relatively simple to fit (he says). a few photos might help.

Aye switch will be goosed, Its usually always the switch on the handle. Open the actual switch if you can (screws ?) and it should be apparent whats broken.
Let me ask you one question. Is your money that good. Will it buy you forgiveness. Do you think that it could. I think you will find When your death takes its toll All the money you made Will never buy back your soul.

I've removed the switch but not tested it yet. It doesn't look like you can open it. There was a small cable tie on it which I've cut off but still struggling to open it.

Ah. White switch ? Thise ones are sealed. Not sure how you could test it with a multimeter sorry.

Thats the one. I was thinking it would be a case of turning the switch and then having the probes on the relevant outputs?
Failing that i could just buy one of the bison ones online. They have all the same connectors and give that a try. If it still doesn't work then can always resell the part and either try the bushes or just buy a new engine.... i was thinking about it but i'm a bit skint at the mo so was trying to keep this one if possible.

Would need power going through it while testing. Havnt got a clue which wires to test as im certain there are less wires coming off the switch than there are selectable speeds :scratch:

check the pin where the negative battery cable attaches though. Does it look out of place compared to the positive one, has it melted the plastic around the pin, is it wiggly ?

Ive fixed loads like that. Temp fix for that was heating the pin to soften the plastic scitch then tap the pin back in.

If you plan to crack it open for a look, If selecting speeds feels different than before (sticks, clicks, loose feel etc) inside the switch is a circular disk (the shaft where the handle attaches to the switch) there is a ball bearing and spring so watch out for it :giggle: under the disc is a plastic peg which moves when the disc turns (handle turned) this peg basically bridges some pins to send power down to the motor. The peg breaks, doesnt move select any speed but there is no power going to the motor.

What i think happened with that outboard was the ball bearing came out of its place, jamed the thing from turning then someones turned it too hard and broke the peg inside the switch. New peg and it worked a treat.

Sometimes though inside the switch are metal plates and with the disc turning and the pins rubbing from one pin to another it picks up plastic and coats the metal plates and pins blocking a good connection for power.

If its none of the above then down at the motor inside line can get caught up. Ive seen that stop a prop dead and it was just thin mono. If not line then insude the motor itself the braided copper wire with the bushes on the end can heat up become brittle and fray or corrode and break or get p**s poor connection.

Also seen one where the bushes that sit on the copper bit of the motor deposits a layer of something over it. dunno if you have tried it but a good way to test if the bushings are f****d is to select a speed and give it a couple of kicks and if the prop moves at all then its probably the motor (ive fixed 2 like this)

If you're not in a rush i can try see if i can find a switch that works a little bit (one or two speeds from another outboard i fixed with a new switch) to confirm if its your swith) but could be a week or two.

Cheers Andrew, I'll have a mess around with it tonight and see if I can figure it out.
The switch feels like something has changed with it. Previously it was very smooth and since its not been working it feels a little "crunchy". Its especially difficult to go from Reverse 2 to reverse 3 and back.

I'll connect up the power to the switch and see if there's any life on any of the settings.

There are also 2 little U shaped copper bits that sit on top of the peg. Ive seen them come off the peg or not seated properly. That could be the crunching.
