Tohatsu on the Green and Colorado
Couple spare impellers and a spare prop nut and pins.
Couple spare props.
Carb rebuild kit.
Couple fuel filters.
Impeller has lasted from purchase to present time, 5 years, 8-900 miles of silty river operation.
Props last a long time at low throttle operation. Bring a file.
Crap in fuel, sandstorms, storm fronts moving through, eventually carbs clog and will not run slow or idle. Two rebuilds for me in same time period mentioned above. Bring something to poke out the jet with. Small-stranded wire.
