A 13-foot inflatable boat powered by a 25 hp Evinrude motor can typically reach speeds of around 20 to 30 knots, depending on factors such as weight, load, and water conditions. Generally, with optimal conditions and a light load, you might expect closer to the higher end of that range. However, performance can vary, so it's best to check with specific boat and engine performance data for more precise estimates.
I have a 2.7m Inflatable boat and have a 2.5hp Marriner engine the engine will allow the boat to cruise at around 8knots and that is with 3 of us in the boat.
About 240 MPH

First, it needs to be mounted on the boat. And the boat determines how fast the attached motor will go. If the boat is wood, then it will likely float deeper in the water, and not be particularly fast. If the boat is a smaller fiberglas one, then the motor and boat will go faster. Based on much boating experience, I would say that most boats could go 30 to 35 mph with the 40hp Merc.

it is very fast
19 mph
A BIG engine or electric motor.. Or a BIG sail.
Depends on how fast the boat is traveling. On a boat traveling at 30 mph it will take 30 minutes.
on my avon air floor inflatable in okinawa with 2 and fishing gear about 4 to 6 mph. avon 310
About 10 to 12 on plane
