You can find the Mercruiser Service Manual at boatinfo.no/lib/mercruiser/manuals/mercruiser2.html#/0 It's free. You need to have the latest version of Adobe Flash on your computer to open it.

I have a 1972 Sea Ray SRV 190. Same engine. The restoration is at newboatbuilders.com/pages/SeaRay190.html

Actually the wiring on theses is pretty basic 12V DC wiring. I updated mine with a Battery Switch, a fuse block back near the battery and a fuse block under the dash where all the instruments and switches are. A lot of the wire needed replacing. (all of it in fact) I also installed a kill switch with a lanyard and a new ignition key switch (the old one was kaput) But mostly it is all a matter of replacing old wire and switches, and maybe instruments. Mine needs a new tach, which I have but haven't installed yet and a new speedometer. The hour meter doesn't work either but I really don't care.

Good luck with your project. If you need any advice just ask.
