I own a 16 foot fishing aluminum boat with a 40hp 2-stroke outboard. I have been able to get it up to 32 mph in calm water, with the tilt/trim adjusted. With a boat full of people and gear it only goes in the mid-20s, but for most smaller lakes, that's plenty fast.

This depends on several factors, the most important being the size and weight (or displacement) of the hull. Other factors are the shape of the hull (deep V, planing hull, displacement hull, etc), and the size and pitch of the propeller.
If you put the 40 hp mercury on a lightweight 10-foot racing hull, and used a speed prop it would probably go 40 knots or better. If you use it to push a 45-foot yacht with a 14-foot beam (width), weighing several tons. you have a large trolling motor.

Seattle is right, hard to tell without more info. A 5.5hp wont get that boat on plane, so you will be pushing through the water instead of riding on top of the water. A 20hp should get you on plane and increase speed quite a bit. Check the plate on the transom, it should tell you max hp for your boat. You don't need max to have fun, 20hp or so should do it. Keep an eye out for used one, test in water & in gear before you buy. Have fun, stay safe.

A 16 foot runabout might break 35.
