I'll be coming to the Forty Mile river this summer to do some gold mining and need to get a boat to run back and forth on the river with. Been doing a lot of research to figure out what I need but still can't decide. Looking at either a jet foot outboard or a 27hp or larger surface drive mud motor. Which would be the better choice for running a river that can get very low, with large boulders in it? I'm leaning toward the mud motor right now, because of the fuel economy and the simplicity of them. Does anyone run a mud motor in conditions like this? Also, what hull would y'all be running in very shallow water but where I can carry a load? Will be taking a gold dredge up and down river so it's going to be a lot of weight. Thanks for the help!
