As I said before, the occasional trip up 20 mile or Little Sue.
Light boat, 50 hp jet, 2 adults and fishing gear
And it’s not enough power for the Kenai or the rivers I mentioned?
A Tohatsu 40 HP jet has a 60 HP powerhead. People used to run 40 hp on the Kenai in much heavier boats.
Hull shape has a huge impact on performance. Really long and narrow needs far less power.
