Help in identifying electrical part

Click image for larger version

Can someone tell me what this part is called and where to get one? The one wire coming from the left hand side is actually detached and prevents the motor from starting off the key.

Thank you

That just looks like an inline fuse holder and maybe a previous owners mod..

Yup agree with LT, looks like a bodge job. It needs cutting out & a proper job making of it. A waterproof fuse holder & heatshrink crimps would be a start. I'm also guessing if that cable isn't tinned copper, it will also be u/s

Thank you, it is probably a mod as it is an ex RNLI engine so I presume has been altered to allow for electric start. It is a 40hp Mariner circa 2006, any idea what fuse size this would be for?

Without knowing what the fuse is supplying & the size of the cable it's difficult to say. Generally fuses are there to protect the supply cables not the attached load.

I'd use something like this

Or this

The obvious think would be the size currently in the holder! Failing that findthe wiring diagram for the equivalent 40hp. My guess is it will be 20A the same as on my20HP.

That looks like a bit of "after market" wiring to me. Looks like someone has taken a live feed off the solenoid, the 4 core that it connects to doesn't look to be up to carrying 20A

Itís definitely not original - but I guessed follows the same approach as the OEM version - I didnít spot the other end it was joined to on my phone. My wee engine has a waterproof inline fuse in roughly that location. I wouldnít be surprised if itís got a 20amp fuse though! It doesnít look like it was fitted by someone with too much knowledge - and it may all need rewiring.

I've just had a closer look at the cable & if I'm not mistaken it's trailer cable. They've used the white for something else & cut off the green & brown. It certainly won't be tinned. Assuming Finagle's law applies, I'd rip it out & do it reyt.

Thanks for all of your replies. It isnt the neatest of jobs so I will probably look at rewiring, does anyone know where I can get a manual / diagram of the electrics?
It is a 2006 Mariner 40hp 2 stroke.
