How much faster will a 200 HP outboard go vs 150 on typical bass boat?

The speed difference between a 200 HP and a 150 HP outboard motor on a typical bass boat will depend on several factors, including the weight and design of the boat, the propeller size and pitch, and the conditions in which the boat is being operated. In general, a 200 HP outboard will provide a higher top speed than a 150 HP outboard, but the difference in speed may not be significant.

As a rough estimate, a 200 HP outboard may provide a top speed of around 55-60 mph on a typical bass boat, while a 150 HP outboard may provide a top speed of around 50-55 mph. However, these figures are just estimates and the actual speed difference will vary depending on the specific boat and conditions.

It's important to note that the speed of a boat is not just determined by the horsepower of the outboard motor. Other factors such as the weight and design of the boat, the propeller size and pitch, and the conditions in which the boat is being operated can all have a significant impact on speed.
