Nope,
It is still illegal to have a gas outboard on a lake that doesn't allow them.
I had a buddy who covered his outboard with a plastic garbage bag,
and had it trimmed all the way up,
and he still got a ticket. I have heard about removing the prop,
but I wouldn't risk it.
You know how the WDFW officers can be.
You almost need a Lawyer to be an angler in this state.
