Re: evinrude 10hp qd-23
You should be able to inspect the coils, points, and condensors without taking the flywheel off. Sometimes the flywheel can be a pain to get off. There should be a small plate on the top of the flywheel held on by two screws. If you remove that plate, you should be able to slowly turn the flywheel and look at each part. There are 2 coils, 2 points, and 2 condensors. The coils are the big round things. When you look at them, you want to check for cracks in the outer part of the coil. If there are any cracks, they should be replaced. When you look at the points (contact points), they will look like 2 metal pieces that come together with springs attached. The purpose of the contact points is to open and close at the right time to send the spark to the spark plug. Each point controls a different cylinder. The main thing you want to make sure with your points is that they are making good contact.
Of course, if you find cracks in your coils, you will want to replace everything, because everything is probably pretty old.
