Which is better 2 stroke or 4-stroke outboard motor?
Because a 2-stroke engine only uses two piston strokes to generate one revolution of crankshaft power, it generates much more power than a 4-stroke engine of the same horsepower. This gives 2-strokes better top-end speed and acceleration. 2-stroke outboards are ideal for use on smaller boats.
What is the biggest motor you can put on a 12 foot boat?
For example, a twelve-foot boat with a four-foot transom width translates into a maximum engine size of fifteen horsepower.
Why do they make a 9.9 outboard?
It’s either that or a boat licence (like car tax for cars) or something similar. Therefore a 9.9hp allows you the biggest engine without needing a licence. For a small RIB or a yacht or a non planing boat this is therefore a popular choice.
How fast does a 9.9 hp boat motor go?

What is the lightest 90 hp outboard?
Suzuki DF90At 155kg, the Suzuki DF90 is the lightest 90hp 4-stroke engine currently on the market.
Why is 9.9 HP not 10 hp?
The block on the 9.9 and 15hp models are the same but the carb is different to restrict fuel input so lots of 9.9 owners are bolting on the higher end carbs to give them 15hp and still have a owners manual and serial number and cover that say 9.9hp.
How fast is a 10 horsepower motor?
As a practical matter , you can get from fifty to maybe eighty mph with a ten hp engine on a light weight motorcycle if you tuck in and have a good fairing . This means a racing style bike at the hight end. May be twenty five to thirty five mph in a light weight automobile with low aero drag on a level road.
How fast does a 8 hp motor go?
Power packed: 8hp outboards All except the lower-powered Torqeedo managed top speeds of around 14 knots in flat water.
Why do boats have 3 motors?
Going from three to four outboards on the same boat usually increases speed, but not proportionately to the increase in horsepower. Even though you boost the power by a third, the weight and drag of the fourth outboard prevents a corresponding increase in velocity. … Its lower unit also generates additional drag.
Who made the first outboard motor?
Ole EvinrudeOutboard motor/InventorsOle Evinrude, (born April 19, 1877, Norway—died July 12, 1934, Milwaukee), Norwegian-American inventor of the first commercially successful outboard marine internal-combustion engine.

Why do boats have so many motors?
Compared with all three other propulsion systems that basically have an engine in the boat, using multiple outboards makes the boat faster because of a beneficial power-to-weight ratio and, in most cases, the outboards are more fuel-efficient.
How fast will a 9.5 Evinrude go?
The fastest theoretical speed would be with the highest stock propeller pitch (9) at maximum 5000 RPM and no slip – that would be 24 MPH.
Who makes the best 9.9 hp outboard motor?
Yamaha also produces a “high-thrust” 9.9-horsepower model, which provides up to twice the thrust of comparable 9.9 models, thanks to a large-diameter propeller. While not as well-known as some other brands, Suzuki manufacturers some of the nicest and most durable outboards on the market.

Who makes the best 2.5 hp outboard motor?
YamahaRe: Best 2.5hp outboard Best small outboards are by far either Yamaha or Tohatsu 2 strokes. They can be difficult to come by though as 2strokes are no longer manufactured in North America (I believe since 2006ish). Keep an eye out on craigslist. That said, if you are gonna go 2.5 I’d really suggest just going electric.
