Got a 115 on the back of a pontoon, maybe 150 hours on the engine. Starts and runs great. Good water pressure out of telltale. Will run at 45-4700 all day long, cruising, pulling a tube, no issue. At around 4900-5000, after a few minutes I will get the death shake and 6 beeps. If I'm quick with the throttle, I can get it down to around 3000 and it will stop beeping and the de-rate clears and I can go back to 4500 for as long as you want to run it. Go back to around 5,000 and shortly it will do the 6 beeps again and violently shake until I get it down below 3k or I just throw it in neutral usually. Can't be an overheat type deal, as it clears instantaneously when you drop the throttle, and will run for awhile at WOT before it does it again. Very aggravating. SEEMS to do it more often when turning, but can't be sure of that. I want to say it sounds like the neutral safety switch, only because the 3,000 mark (or thereabouts) clears it, and I think that's the neutral RPM range. Not really sure why that narrow of a band would cause it, especially with several minutes delay in between faults. Seems it would always do it once you hit that RPM if it was the sensor bad or something out of adjustment. Hate to drag it out of the slip and trailer it to the dealer if it's something simple. Was going to try to start it and unplug the switch and run it the other day, but the sun was beating down and I looked for about 2 minutes and didn't find it quickly where I could unplug it (not in the spot of the one I saw on a youtube video). Any ideas? No sticky fault, even if I shut it off when the fault is happening, guardian only beeps the one check beep when I turn it on and all is well.
