So, the turtle build being on schedule with turtle speed, I decided it was time to drain the gas today. Easy job, but a little messy. 17mm socket needed. Look for the drain bolt nestled inside the large skid plate hole. There is a rubber gasket on the drain bolt. Page SF-36 of FSM does not show any torque spec and the gasket is NOT listed as a nonreuseable part like a couple of others. However, it does say replace gaskets. I was expecting to see a crush washer here. So, careful on tightening.
This build is going to start life out with fresh ethanol free gas if it's available when I first fire her up.
