Hello,<br /><br />I have a 1986 V6 200 that needs help! <br /><br />Symptoms: When I hit the water with charged batteries this weekend I could get WOT and the engine ran GREAT! Then after about 5 minutes of this, it started to stutter and I would have to back the throttle off to below 4000rpms, then it would run without stuttering. The engine would be fine as long as I kept it below 4000, but of course, my big boat doesn't get off plane tell 4500 (go figure). I checked to make sure the Ball is hard and it is (pumped it when over 4000 and nothing happened), so fuel flow is not an issue. On my dash gauge and Depth Finder I show 12.0V with engine off and 13.8-14 with the engine on. Now the weird thing is that even with my voltage never dropping below 12.8 when running, I will loose enough amp's to keep my electronics running! After putting around for about an hour at 3800 rpms, my Depth Finder goes blank and I can't use the transom lift for the motor. BUT during this whole time, I still get 13+ readings on my voltmeter???? Then when I finally headed back a new problem happened that I think spawned from this whole issue, it wouldn't shut the motor off. I had to CHOKE the motor off.<br /><br />What I did during to try and fix the problem: I have 2 batteries, when I lost the ability to go WOT I switched it from ALL setting to Battery 1 (to save Battery 2), then later switched to Battery 2 and the SAME RPM issue existed, even in ALL. Then I turned off all the batteries so I was running off the engine alone and nothing changed. You couldn't tell the difference in reaction between battery 1, 2, ALL, or None!<br /><br />Things I did recently to the engine: It has a brand new Stator (put in this week) along with a new flywheel (Lost a magnet in the last one).<br /><br />My first instinct is Voltage Regulator, but I AM getting a voltage increase when the engine is running. Starter Solenoid, maybe, but that won't effect WOT? Lastly Powerpacks.. I actually know nothing about powerpacks so this is where I would like advise. I am a Helicopter Mechanic and restore old cars as a hobby, so the "powerpack" is a little illusive on what it is, what it controls, and how it affects things. I do know that the shut off diode is located in the power pack and there is a method to check it, I will do that, but what about the WOT issue?.<br /><br />Thanks for reading this over and hope someone knows EXACTLY what I am talking about.<br /><br />P.S.
