[118118]

hi,
does anybody know if there is an online manul for a 50hp 4 cylinder twin carb mercury blueband electric start engine. i am trying to sort out the loom, because it is in pieces as someone has replaced the ignition circuit and killcord with a lightswitch!

thanks

I have one of those engines. I also have the manual. Costs £20 on line.

However if you know what wiring diagram you need then I can scan it in and send it to you.

Trouble is the manuals cover all Mercury engines. Be they 10 HP or 200 HP.

If I can help I will, but personally although people were willing to help me when I first got the engine the easiest thing to do in the end was buy my own manual.

I would be quite happy to take photos of my engine if it helps you rebuild it and also give any advice I can.

However I am not a mechanic or electrician, but reference photos do help.

Regards Nick.

I also had to rebuild my Killswitch.

The local 'Arthur Daleys' in Southampton wanted a minimum of £42 for a kill switch. In the end I totally rebuilt mine. Not very pretty but it works.

I spent a whole day driving around all the chandlers in southampton and only found two Mercruiser kill switches, not even Mercury Kill Switches. Either buy a new one on line or rebuild the one you have.

Maybe we could meet up later this year.

I shall be out in the Solent from1 March 2005 and frequent Bembridge and Culver Bay.

Regards Nick R.

hi biggles,
do you have the wireing diagram for where the loom joins the engine. i think the ignition has been hotwired, and now the key starts, but doesnt stop the engine. i have the wireing diagram for where the key switch joins the loom as i have already replaced it.
thanks for your help

Right mate I've had a look in the manual and theres a few wiring diagrams. What I'll do is copy them all and you can choose the one you want.

Can you PM me your E Mail address which will make it easier for me to send them to you.

Regards Biggles.

If the key will start the engine but wont stop it check the black wire with a yellow trace, if you earth out this wire it will (or should) cut the engine.

Pictures on their way. If they are not what you want let me know.

Hes right with the kill switch wiring. Black and yellow needs to go to earth to kill the engine.

On mine it goes through a seperate kill switch which when closed goes to earth and kills it.

A little tip. Don't touch it when the engines running. It hurts.

With regards the pics I couldn't work out where the Kill switch is on that diagram.

Best of luck.

I had been looking for a killswitch a while ago, and got mine from here (E-1120/C with coiled lanyard £9.07 ) They sent it up for a few pounds... Works great and not that expensive... Just a tip for any other people looking for a killswitch!

hi guys, i have a few remaining spares from a blueband 60 including carb's, dissy, electronics box if either of you want to make a sensiable offer. These are worth bundles really but now collecting dust (Just sold gearbox for £50 on ebay - cost £300 to refurb a few years ago) so sensiable offers?

Unfortunatly i don't have a wiring loom or remotes box anymore.

[Mr-d]

I don't know if the 60Blue band has the same internal levers as the 20 Blue band, Im still looking for the internal remote levers for throttle and gears.. i have a remote + cables + barrel joint but dont have the internal bits that it slots into!

Thanks,
Daniel.

[Daniel]

I too have no idea if it's the same but i think i have one! PM or email me what it's worth to you if interested...

[Mr-d]

erk, looks scary... i have no idea what it looks like.. i just know that i need the bits.. Where did that come off? was it on the (if facing side where the controls, pull start, petrol thingie and choke would have been) on the left hand side of the engine? or on the right hand side?

As for price.. i have no idea... no clue what its worth either.. perhaps someone could tell me?

Did your remotes have the barrel type connectors to? with the cross in one end?

Edit: Wait a min.. think i figured it out.. same situation but on Right hand side there is a stud sticking out which it screws onto, the bolt on the "arm" on that pic goes though a hole which is attached to the throttle arrangement, yes?

so is that just the throttle arm that is there?

don't think so, the "arm" connects to the gear selector rod, which turns.

I don't think i can be anymore help, sorry! I took this engine to bits in about 1998... so it's all a bit hazy.

I (think) it came from the PORT side of the engine where the control cabels went in. It provides locators for the two cables, the throttle connects straight onto the assembly that advances the dissy and opens the carb's where as the gear selector has a slide assy an an arm to drive the "rod" that runs through to the gearbox.

Or that's how i remember it.

A tenner plus postage, thow it away if it ain't right!

[Mr-d]

Sounds like a good idea... any idea how much it weighs (for postage i mean) And do you still have the bolt to secure it down with, or is it missing?

How to pay.. do you have paypal? Or should i just write a cheque?

PM me with the info

Thanks,
Daniel.
