I have a 1994 Mecr/Force 120hp. Starts great, and runs very strong. After warm up, it idles down and dies. Then it's hard to start. I have adjusted the idle, but still wants to die and hard start when warm.
Any ideas?

immediately do a spark check(must jump a full 7/16's gap) when its warm and dont want to start....could be a powerpack or other electrical item that is getting warm and shorting out.

Re: 1994 Merc/Force idle trouble

I had a similar problem on my 96force 120. Turns out it was fuel related. There is probably a valve on you fuel tank where the line comes out. I replaced it with regular gas fitting from home depot. problem solved. If you have a clear fuel filter start the boat and watch to see if the filter drains out. The boat will actually run for a short while with only that fuel making it seem like it stalls when the boat warms up.
