Mechanical Issues on motor

Recommended Posts

Hello, I am new to the site and am looking for some help and or suggestions on a mechanical issue I'm currently having with my 1989 Chaparaal 2100SX. Over the weekend My wife and I were out boating on Lake Michigan when we became dead in the water. As we were cruising back to the pier head, the motor acted as if I had turned the ignition switch off. At that point I put the throttle in neutral and turned the switch to off and had a buddy pull us back into the docks.  A brief diagnosis that I was able to do is as follows:  Motor cut off as if I turned the ignition switch off.  I checked the oil dip stick which was full and no signs of leaking oil anywhere. once a thorough look through was conducted I felt that there was no apparent problem, I decided to see if the motor would turn over. Hooked up the muffs and was able to see that the boat was cranking over and there was compression. Gave it a shot of ether to ensure boat was getting fuel, still start. Then I checked the spark plugs, at which I found that we were not getting a spark at any of the plugs I pulled. So here I am looking for some guidance on where to go from here. Any suggestion would be greatly appreciated. Thanks for reading.

Ignition module inside the distributor.  If it's a Merc, PM Shepherd for the upgraded part number as the OEM's were problematic.

Poverty 88,

You may want to look at the neutral kill switch adjustment and/or function. Personally speaking I have a 5.7 Mercruiser 1995 and once in a great while I have "center" the controller. i.e. reverse to forward and find the sweet spot (neutral) You would be surprised. I have assisted a few out on the docks that had the same problem. 

Technically speaking, the neutral switch on the carburetor kills the engine as you go from forward to reverse- Reverse to forward for a split second. A bad adjustment  could have some impact. 

Just a little adder; Wingnut most likely has it. Its been some long since the neutral kill switch acted up I can not remember if it takes out the ignition including starter cranking or just the ignition. 

Let us know what you find...
