I have not fished there in a boat. But there is a log feature about 1/4 a mile down from the launch that would be a problem for a prop boat. It also has a series of rocks just before you get to it that are underwater now. Not sure about the upstream. The fishing in the SnoQ is not worth the potential boat damage IMHO. Take it to the Snohomish and fish near the confluence of the 3 rivers.
