Hi. I am completely new to this, but recently bought an old boat with the above mentioned motor, and I have a factory service manual. The motor was very well maintained and used frequently by the previous owner. It started and ran perfectly both before and after I bought it. So I think my problem my be some kind of user error.
The first time I took the boat out, it started with a single turn of the key, idles and ran perfectly for 25 minutes. I had the throttle wide open for about 5 minutes when the engine suddenly died. It did not sputter or cough, it just shut down, and it has not started since.
I originally thought maybe it was bad fuel and fouled plugs.
Since then I have replaced the fuel, checked plugs (which were new), and verified compression. I have a new battery. I bought a spark detector, and as best I can tell there seems to be no spark between the magneto and the plugs. The points and condensers look new, and it seems strange that they would go bad for both cylinders at exactly the same time anyway.
I am at a bit of a loss, so any ideas would be appreciated. I have a feeling I maybe doing (or have done) somthing simple and stupid.
Thanks.
Mike
