While you can upgrade the jet ski units with better blades, grills, nozzles wear rings etc they don't take the bash as well as bigger units. And if your engine goes pop its an expensive exercise versus going to the wreckers and picking up another engine, plus the bigger two strokes are guzzlers. I find two guys with push poles can shift my boat fine when stuck. If your sole aim is to push up skinny rivers as far as you can then sure a 3M boat is probably the go. If you want to take a decent amount of gear and value your spine a slightly bigger boat might be the better option.
