My Water Skimmer 10 ft boat can go 27 mph. Probably the fastest hull design ever for a small boat. Boat is rated for a 15 hp and that can push the boat well over 30 mph. Unsinkable, glass bottom, replace your dinghy or jet ski.

A 6 hp outboard will go about fast enough to plane a 10 ft. aluminum boat, with one passenger aboard.
8-15
It depends on the size craft it is pushing. A 5hp outboard should run fast enough to plane out say a 10 to 12ft. aluminum boat with one man aboard.
5mph or less
With 1 person in it say 180 lbs. It will go 15-20 mph. This assumes the outboard is running well and the prop in good shape.
246 knots
A 7.5 hp outboard would work for a small, lightweight boat, something along the line of a 10 to 12 ft. aluminum boat.
Speed is dependant on a number of factors. Most importantly the size, type and weight of the boat that it is on and the number of people on board. A 50 HP outboard will push a small aluminum fishing boat a lot fast than it will a 20 ft fiberglass boat. I have a 50 HP 2 stroke that will push a 16 foot aluminum boat 35 MPH.
Yes, but not very fast.
You will notice on the throttle handle that there are three positions on the legend. "Really Slow", "Start" and "Slow".
A 3.5hp outboard will give you 8mph tops, which would be a normal walk to a slow jog.
I have a 14/36 flat boat with a 15 and it goes 26mph with only me and minimal gear.
