Re: I never met an outboard I didn’t like until now – 1960’s 40Hp Evinrude

Just to catch up……

The carb linkages are all attached and verified to be working at each “crank” session when the engine would not start. The engine does not have a kill switch but shuts the engine off with the ignition switch that connects the two mags together. I disconnected one mag from the switch to ensure an intermittent ignition switch was not shorting the mags together. The engine does have the fuel economy linkage and this checked out to be adjusted properly. The vacuum cutout is working properly and tested.

I have been using the ATOM modules on my 1960 Johnson 40Hp for since 1996, on my son’s 1967 33Hp since 1998, another big twin since 2000 and this engine since it was brought back to life 3 years ago. I have never had one module fail and these motors are regular runners.

On all the engines I installed the ATOM modules on I always mount them to the side of the block. When you do this it is imperative that you run a braided ground strap from the block to the mag plate. The current between the magnetos thru the mag plate and the block can be impeded by the grease allowing the mag plate to move with the throttle. I learned this one frustrating day on the water!

Given my history of the ATOM units and never had a failure I find it unlikely that both units failed at shut down on the second barrel run, especially when the visible spark was bright blue when checked. I will be going back to work on this engine next week and will start with the simple first, new spark plugs.

Thanks
