Hoping some of you who have been down this path already could help out a noob TPS wrangler with some advice. I need to change the TPS. I already have the new part with it's little blue o-ring in hand. I looked everywhere and read every thread and watched every video I could find. I cannot locate where the part is on my boat. I removed the flame arrestor from my engine hoping to see a Throttle Position Sensor somewhere below it to yank out. Cant locate it. Is it on the engine, or is it on the throttle assembly up at the helm? I tried removing the throttle assembly and it's not quite straightforward to remove, in order to get behind it and see if the sensor is back there somewhere. Figured I would post here for some guidance before I go crazy. Thank you! The tender is a 270SLX who first set sail in 2012. Mercruiser 350 MAG 5.7L 300hp Thank you!
