Why the big motor

Curious,what is the reason for a 300 HP Motor on a 16 foot boat on rivers and lakes in the US. How fast do Bass or Salmon swim.? Amazing,unsure from Australia

Where did you see something like that?  I'm pretty sure that would be illegal. I don't know of any 16' boat that would be rated for a 300HP motor.

In the United States we have Federal regulations concerning powerboats, both commercial and recreational.


The US Coast Guard enforces these plus we have organizations that have industry accepted standards that many boat builders go by. One is that for boats under 20' long, there has to be tests conducted and placards installed telling the maximum weight allowed and the maximum horsepower allowed.


Racing boats are exempt but all other recreational craft are required to abide by the regulations.


In bass and other fishing tournaments, the boats have to be legal and most 250-300 HP engines are on 20 to 22' boats.


You can peruse many of the regulations online.
