I have an 1989 Evinrude XP 200 on a 201 Stratos. My boat has been at the shop for the past month and today the mechanic called stating that he cannot fix the problem. Here is the senario. I am driving along between 60MPH and 65MPH and the motor hesitates. It picks back up and then shortly after shuts down. The motor will start every time and will idle but when put under any pressure it just boggs down. The mechanic says that the number 5 cylinder will not fire and that he has tried everything and cant figure it out. The power pack has been replaced, all 6 coils, the stater, fly wheel, wiring harness and practically everything else.

I brought the boat home still not fixed. I am at a loss. If anyone has any ideas PLEASE let me know.

Thanks in advance, Scott
