Andy,

You could use something like this

https://www.ebay.co.uk/i/172632490773?c ... 426&crdt=0

You will need to work out what the max current draw of your motor is and go for a controller around 25% greater.

just started seeing these after broadening search terms :thumbs: im wondering though, with these it looks like you need to have the outboard set full speed using its own speed switch in the handle, like an on/off, then using that device to control it ?

I would bypass the outboard speed control completely and just use the variable.

Will need to figure that out. The origonal speed switches are forever breaking at £33 a pop. New infinite speed circuitboard in the head and a little pot right on end of the handle. Well thats the idea for now :giggle: two way pot for reverse instead of a switch would be ideal for my idea instead of a seperate box.

Minn kota, manage to do it on the pot but their boards are a bit more than the ebay special.

Yep. Still happens from time to time reckon that was just the shity clamps and corrosion on wire and clamp. They go ok for a while after cleaning up the contacts and crimping them on again..... till they tarnish.

Theres a few with broken switches i could diy. the price of the switches keep going up and are not far off £40. Customers can be a bit heavy handed.

A 30p pot is a whole lot better to replace than a 38 quid switch :giggle:

Could be they are flicking on/off a lot, a variable would help with that.

Sounds a lot for a rotary switch, are you buying as oem part or generic?

Shakespear ones i think he gets. Can get generic but seems all mostly from states and china. After shipping would be just about same if not more.

The shakespear one looks like a standard 6 terminal rotary switch in a housing, have you tried taking the switch apart and seeing what's inside? You maybe able to source the switch unit separately a lot cheaper.

If you chuck one on the post to me, I will take a look and see if they are possible to repair.

Google PWN speed controller circuits and brush up on the theory.
Basically a couple of heavy duty transistors that switch on/off pretty rapid.
Frequency controls speed rather than voltage.
Might allso wanna get a can of servisol super 10 for cleaning them switches.
PS cheapo 12/24v chink scooter controllers are prob up to the job.
