83 johnson 90 no spark

[chitty024]

If you stand at the back of the engine the 2 cylinders on the right are not getting spark. I put brand new plugs in. tried wires on both sides they work. don't know where to go from here. Ive looked at other parts in the system but they are expensive and i don't want to just start buying stuff and it not be the problem. Any help is greatly appreciated!

You should get a manual for your engine. You can use the trouble shooting section to help you find your problem. The are a lot of electrical connections and components that could cause your problem. There is a power pack on your engine for the ignition system, relies on a good electrical system to operate properly.

check your coils...they are not too very expensive and it doesnt hurt to replace them every 5 years or so any way...then you can check and make sure you are getting 12V to the coil from the power pack, check it while turning it over with the plugs out of the engine...and like the previous post said check all of your connections good.
Good luck Sparkie

you have 2 power packs on that motor, one for the right bank on for the left bank. sounds like you need a power pack. my research say this is the replacement.
