Hello Everyone,<br /><br />This is my first post. Here is my problem. Just got boat back from shop with a minor tuneup, plugs, timing, carb sync, and lower end lubed. The other afternoon took boat for spin. Got her out in the lake, and she popped right up on plane and was running about 5500 rpm. Then all of a sudden she cut rpms and started to spit and cough, and shake violently. Shut it down and restarted. Could not go above 2800 rpms. Would shake and miss badly. Cruised back to the dock at low rpms. Learned it was going into slow mode. The funny thing is that it never gave and alarm. Got mech on it, and he is stumped. He performed several tests. Compression good, has spark until 2800 rpms then all cylinders shutdown, until dropped below 2800 rpms. Tested stator, and checked good with meter, disconected temp switches and still no go. unhooked vro and still no go. Unhooked slow mode wire in power pack, and still would not run above 2800 rpms. Fuel is new, and getting plenty of it. Primer bulb stays hard. Forgot to mention I replaced the voltage/rectifier last year. Tach is also very erratic, even with wire directly to stator. Any help would be appreciated. Joe if your out there, your input would be appreciated.
<br /><br />You have an Evinrude trouble. There is a forum for troubles and repairs. I will move this there.
