That s/n comes up as :

75 75 (R4) 4-cyl 6613221 0A197881 1985 USA

From here:

http://www.marinshopen.se/Motorer/O...Mercury2takt4cyl4085hp/tabid/487/Default.aspx

It is a model:

1075625 MERCURY 1985 75

Parts listing:

http://www.crowleymarine.com/mercury-outboard/277.cfm

Here is a link to the condensed version of the service manual. Let the page load for several seconds, then download soonest to your computer as the link is short lived.

http://web.ebscohost.com/serrc/pdf?...e-8d05-d15e12bbd92f@sessionmgr15&vid=4&hid=14

You will see that your s/n is the Thunderbolt without Disributor as seen in Fig M12-58.

Sorry I couldn't find you a coloured version.

still having no luck ,only thing i have from the controls to the motor is power but my trim and tilt is also still not working, and i just chaged the siliods for the trim and tilt, all it does when i hit the button is click ,so if you have or know where i can download a compleate wiring diagram from the tilt motor to the siliniods then to the harness or where ever i have to go to get it working that would be great. and any info on the motor itself would help as well ,theres power to it but that it wont tunr over ,wont click as far as starting dead , but motor is not seized and is in nuetral

I just checked the link and it is still working but you must have Adobe reader to enable you to see the files. Do you have this on your computer?
