What kind of engine is a 1956 Johnson Seahorse?
CD-13 is 1956 Johnson 5.5 hp. ‘A’ is not clear to me. You definately have magneto ignition with points and condenser if a ’56. So most likely it’s the points. Here’s a tip: Points are often interchangable beween a wide variety of engines from different makers.
How do you test an old Johnson Seahorse engine?
Disconnect that and tape over it to ensure it doesn’t inadvertantly ground while testing. Remove the plug wire and plug and put the plug back in the boot. Rest the plug against bare exposed metal of the engine anywhere convenient. Check for spark. Should be blue/purple and make a tiny click. Red is no good.

Discussion in ‘ Outboards ‘ started by Header108, May 22, 2007 . Just bought this motor at a yard sale owner said it ran great but after I installed new gas and oil and tried it out it would not run? Carb is getting gas but looks like no spark from plugs,should i replace the plugs first and retry and if no spark what is next?
What happens to the points on a spark plug?
The points send voltage to the spark plug wire and onto the spark plug. Ignition points can suffer from wear, carbon soot and burning. When the point contacts wear or accumulate carbon buildup, the dwell (ignition timing) changes, resulting in a poorly running engine. Place the motor, if trailered, in an accessible spot.
What causes a spark plug to wear out?
The points send voltage to the spark plug wire and onto the spark plug. Ignition points can suffer from wear, carbon soot and burning. When the point contacts wear or accumulate carbon buildup, the dwell (ignition timing) changes, resulting in a poorly running engine.
