I'm running a 1978 Mercury 90hp. inline six on my 17',distributer ignition. I'm getting 17-18 volts to the battery. I want to add a GPS/fishfinder this spring. How do I bring down the voltage?

that much going in could damage your battery,, in any case the output will still be 12v

George- I went through a similar situation with my 1987 70 hp Johnson. This link I provided seems more specific to Mercury, but it includes a link to a thread I started way back with the same over charging situation in my Johnson. My battery was boiling over and swelling, burned out my Humminbird too! In the end Gwinnett Marine fixed the problem for a decent price. Hope this helps-k

Kevin, Thanks I stopped by Gwinnett Marine today, they were very helpful,parts guy checked several books was not sure he could help but said he would do additional research.He suggested I do the same as electrical parts were not returnable.The hunt continues.

Mercury used to offer a voltage regulator accessory for the in-line 6's. It's simple to install. I installed them on my own in-lines. Cost about $80 each if I remember correctly. Try your Merc dealer.
