Potentiometer issues...2006 20V

[BSHWHCKR]

I'm the original owner of my 06' 20V. Fantastic boat BTW. My kids have grown up on this boat. I had a problem with a low RPM/neutral alarm for the last month and was not able to diagnose it. This causes a "sleep mode" in the throttle allowing you to be in gear but no RPMs over Idle. It can be reset by shutting down and then restarting the engine. Called the dealer in Cali to no avail. Then after checking and even in some cases preventatively changing out various sensors I met another Tige' owner in Lake Havasu City wherein he helped me out. BIG thanks BTW!!! He explained that the potentiometers in Tige's go bad about 50% of the time by about the five to ten year mark. Easy swap out on my boat but may be a bit more difficult on some of the newer boats if access is covered by cosmetic panels. DO NOT buy this part from the dealer as they will charge you an arm and a leg for it....quoted me $230.00....LOLOL I purchased mine off of E-BAY for $25.00. The Manufacturer charges $58.00 + shipping. Hope this helps anyone with the same problem....God knows that alarm noise made me want to put my fist through the dash!!!

Where exactly is the potentiometer located? I have a 05 22v and this summer has been a electrical nightmare (last summer mechanical). I haven't had this problem but with the way it's been lately I am sure it's coming. If next summer starts like the last two, there will be a 22V for sale. Btw thanks for sharing.

Given the "cosmetic panel" comment, it's probably the pot that senses the position of the driver's throttle lever. Normally those are actually a dual pot, for safety. The two are ganged together and the ECU expects them to track to within a close tolerance. If they get out of sync, "something is wrong" and for safety's sake the engine's RPM's are limited. Think of it this way: If you were the engine, and you got two wildly different throttle requests, which one do you trust? The one that says "idle" or the one that says "full throttle"? The safe thing is to go slow until the problem is fixed.
