Sorry for a stupid question. but what the hell is a "little hydro" and how can it do 60 with a 9.9?

hello if your in canada you dont need a licence until 2009 unless its a jet ski also as for speed if its going on a small aluminum boat it will go farily quick wont break records.
Kieran, from your sig I assume you're in Australia? Those Canadian regs probably don't extend quite that far. [links]
30 foot sailboat = 6 miles an hour<br />10 foot john boat = 10 miles an hour<br />12 foot v hull = 20 miles an hour***
I have an 8 hp Mercury on a 14 foot flatbottom and it will top out at about 16 mph with just me in the boat. You should see at least the same or better speed [links]
Shoot, I've got a 4 stroke 5hp, and with just me and some fishing equipment in a 14' jonboat I go 15mph.<br /><br />Crack open that 9.9 and you'll see about 20-25 at least! more
Calculate the horsepower or CC by multiplying or dividing by 15. The general rule is for every 15 CC there is 1 HP. For example, for a 150 CC engine you would take 150 divided by 15, which equals 10 HP. [links]
Also to know is, How many cc is a 16 hp motor? Specifications

Many people have asked for a relationship between horsepower and cc or how many cc in a hp. The short answer is about 14 to 17cc = 1 hp or about 1 cu.in. Thereof, how many cc is a 10 hp engine?Feb 10, 2020
Thereof, How many cc is 16hp?
Subsequently, question is, How many cc is a 5 hp motor? That is about 16.4cc Per horsepower. Reality is a lot different. more
Also, How many cc is a 8hp Briggs? more
When a boat reaches planing speed, the bow will lift above the surface of the water. As the boat returns to level, the only point of contact becomes the propeller just under the surface. In a real sense, the boat flies. An 8hp outboard motor has sufficient power to push a small craft up to 20 miles per hour and bring it to a plane. [links]
The generally less expensive 2-stroke motor is smaller and simpler in design. It has better acceleration and more power relative to its weight. A mixture of gasoline and a motor oil additive is required to fuel it. Some models have electronic ignition, but most have starters that are engaged by spring-loaded rip cords. If the 8hp outboard is an emergency backup motor, a “kicker” for stability and drift control, or a separate motor dedicated to trolling fishing lines, this might be the right choice. more
And 8hp outboard motor is an engine that generates 8 horsepower of energy. They are available in both 2-stroke and 4-stroke designs. The latter design is akin to a small car engine, while the former to that of a motorcycle. Most models employ an extending tiller for steering and accelerating. Many have hydrofoils designed into the shafts to improve the propeller’s thrust dynamic.
The choice between 2-stroke and 4-stroke is mostly a matter of preference and function. If an 8hp outboard motor is the boat’s main propulsion secured to the center of the rear transom, the 4-stroke might be the right choice. It burns fuel relatively quietly, efficiently, and cleanly. Most have an electronic ignition switch to start and stop it.
A boat with a gross weight of a half-ton, such as a small pontoon party boat, is approximately the upper limit of practicality. An 8hp motor will labor to budge a boat this heavy and, in any case, a manufacturer will have specified a minimum power recommendation. For the lower limit watercraft suitable for an 8hp outboard engine, the important factor is not so much the weight of the boat but rather its structural design, especially its hull. The key here is whether the craft is capable of, and stable when, “planing.” more
The 8hp outboard motor is ideal for trolling both live bait and lures to angle for a variety of fish species. At maximum thrust, even on a 20-foot ocean craft, it can attain enough speed to entice aggressive pelagic predators. It can also throttle down a ski or bass fishing boat to slowly track the contours of a dammed impoundment for suspended schools of panfish. more

Quick science lesson: As long as the boat (and all that’s in it) weighs less than the weight of the water it displaces, it will float. This principle remains constant for Jon Boats all the way up to cruise ships.
Sample Size: here
Generally speaking, you want to limit the amount of buildup and external objects (algae, barnacles, etc.) you have on the bottom of your boat. Anything other than an extremely smooth (and clean) bottom surface just adds more drag to your boat and slows it down.
All of that to say, simply tweaking the weight distribution of your boat (usually towards the center) and ensuring that you can effectively plane out during cruise will make a huge impact on your top speed.

25-30mph can be expected at this boat size, which is driven by a 30-35hp engine on average. A 16-footer will also start to carry up to 4 people, so this speed will definitely depend on how much you’re carrying, as well as the arrangement of the weight itself. here
