ITS ALIVE. Sounds like an Opti. Not particularly quiet. Take the cowl off and it sounds like a combine. Alarm alerts over 2000 rpm in neutral, I think it is supposed to. I got a small water leak where I didn't clamp a hose and I gotta look into the shift linkage not getting to the end of the throw going into forward gear. Idles correctly at approx 600 rpm. No alarms. No noticable rattles or hiccups. I lucked out that I did not have to change the harness, all my analog stuff works with the Opti. I may have a winner here. Rained and got dark at around 8:00. A tie wrap or two to finish her up. You couldn't remove the grin on my face with a chisel right now.. LAKE TEST!!
