Start with the basics.<br />Kill switch?<br />Loose or broken wiring?<br />Bad ground wire?<br />Corrosion?<br />Blown Fuse?<br /><br />If these check out, then its time to check the ignition.

Re: 1985 evinrude 28 hp no spark

I need basics for sure. Which is the power pack? I see the coils are on the rear, and a module to the left of the coils oppsite the plugs.<br />Is this the power pack? It is about 2" wide and 4" long with a bolt in each end. All this looking at the motor from the rear.<br />We will try your suggestions and thank you for them.<br />MAZADO

Hi Mazado<br /><br />Yep the module to the left is the Powerpack. Start with cleaning all connectors, including the ground which is probably attached to a bolt on exhaust water jacket. Disconnect the kill wire. If you loose spark on both you can have: <br />bad connections, bad power pack, bad charge coil in stator or bad trigger coil. If you have a manual it is possible to mesure current and resistance in the components, and find the bad one, instead of just buying/swapping parts.

Hi Dane,<br />Thanks for the help, little by little I will eliminate some of these things. Now I at least<br />know where the power pack is. It is where I guessed, but need to know.<br />Thanks<br />Jim

You will save yourself a lot of pain and probably a dollar or two if you buy an OMC shop and parts manual for your motor. They have step by step "how to's" beyond what you will find here.

Re: 1985 evinrude 28 hp no spark

Mazado, regarding disconnecting your kill sw wire. If your motor is similar to my 1980 35hp Johnson, out of your powerpack you will see a black and yellow wire that goes off into a round rubber plug with the 2 orange coil wires. If you pull this black and yellow wire out of that plug you can elliminate the kill sw and kill wire in long wire loom from being a suspect problem. Take care pulling this wire out. I had to feed a small pair of tweesers down along side of pin inside plug to release pin from plug. If your engine shows a spark with this wire removed and not touching anything, then your onto the problem.<br />Dont touch this exposed wire whilst cranking or you will get one big shock.
