    4 s question

    what is the round knob in front of the engine mounted trim switch? I looked through manual and seen no reference to it. It turns 1/4 turn, like a fuel shut off?

    Take cowling off where you can see it. You take the plug out and the hose extends out where you can attach a hose for flushing.

    Best to work it back and forth to get it loosened up in the socket then it should come out. I put Super Lube on mine and it comes out easy now.
