What You'll Learn
A 90hp boat can reach speeds of 41+ mph
The speed of a 90hp boat will depend on a number of factors, including the weight of the boat, the number of people on board, the amount of fuel and the type of propeller. For example, one user reported that their 90hp boat could reach 43-44 mph with a little extra pull, while another said their boat topped out at 30-32 mph with a different propeller.
The year and model of the boat and its engine will also impact its top speed. For example, a 1999 Mercury 90HP 2-stroke engine on a 17ft boat reached speeds in the low to mid-50s. Meanwhile, a 1989 90hp boat with a 16ft bass boat and an aluminium prop reached 41 mph.
Overall, it seems that a 90hp boat can typically reach speeds of around 40-50 mph, depending on a variety of factors.

A 90hp boat can reach 42mph with an 880-pound boat
A 90hp boat can reach speeds of 41-44mph, with one user reporting a speed of 42mph with an 880-pound boat. The speed of a 90hp boat will depend on a number of factors, including the weight of the boat, the number of passengers, the type of propeller, and the rpm. For example, one user reported a top speed of 30-32mph with a 6000rpm aluminium Solas 13.5dx13p propeller. Another user reported a speed of 41mph with two people, three batteries, and 18 gallons of gas. The age of the boat and its engine may also be a factor, with one user reporting a top speed of 41+mph with a 1991 90hp boat, while another user's 1989 model with the same horsepower reached 41mph.

A 90hp boat can reach 30-32mph with an aluminium Solas 13.5dx13p prop
A 90hp boat can reach speeds of 30-32mph with an aluminium Solas 13.5dx13p prop. The speed of a 90hp boat depends on a number of factors, including the weight of the boat, the number of people on board, the type of prop, and the model of the boat. For example, a 1989 90hp boat with a 14x17 alum prop and two people on board can reach 41 mph, while a 1982 90hp boat with one person on board and a 13-1/4 x 17 aluminium prop can reach 42mph. A 90hp Johnson outboard on a 16ft Chrysler Tri-Hull with two men and gear on board may have a lower top speed. A 90hp Mercury 2-stroke on a 17ft boat can reach speeds in the low to mid-50s with the right prop, and a speed of 47km/h with two people on board.

A 90hp boat can reach 44mph with a 19 prop
A 90hp boat can reach a top speed of 44mph with a 19 prop. This is based on a 1982 90hp boat with one person on board. The speed may vary depending on the weight of the boat, the number of people on board, and other factors such as water conditions.
The speed of a 90hp boat can also be affected by the type of prop used. For example, an aluminium Solas 13.5dx13p prop can make the boat "fly out of the water" but tops out at 30-32mph. A 17" prop is good for all-around performance but not made for high speed.
To increase the speed of a 90hp boat, you can try raising the motor and retesting, or consider upgrading to a larger prop. For example, a 19" prop may provide a slight increase in speed compared to a 17" prop.
It's important to note that the top speed of a 90hp boat will also depend on the model and year of the boat, as well as the condition of the engine and other factors.
