Err well I'm no boating expert, but looking at the vid I would say there is no way that dingy will take a doubling of power. It seems to be moving along pretty nicely and you're already getting fair bit of lift of the bow.
But like I said, I'm no expert. My boating experience is limited to sailing 16ft wayfarers.
It can take much more than 5, yesterday i found this vid with exactly the same boat as me o_O http://www.youtube.com/watch?v=bulN6UtxTtU
My personal preference on brand would be Mercury, but genuine parts and dealer service charges are usually higher than OMC (Johnson and Evinrude). The reliablity of Johnson outboards is better than some cheaper name *cough* Tohatsu *cough* brands and parts are readily available. I have a 1972 4hp 2 stroke Johnson (found seized at the local landfill) put in 2 main crank bearings, added fuel, 3 pulls and it runs like a clock.
My advice would be to get the 9.9hp Johnson, just make sure you get the correct pitch propeller for the approx maximum combined mass of the boat, motor, passengers and gear (if any, not much room on a 2.7m blow up doll)

Just got an email, that i can trade mine in and have to pay 1500 euro for a new Johnson 10hp.
It can't take more than 10. No, it won't explode or sink instantly, but the glued backplate will eventually separate from the inflatable tubes.
Why bother with more anyway, 10hp already turns it into a rocket.
I dont want more than 10 10 is enough for me. 
10 is enough for me. I would go for the Yamaha if it was my choice. 
Ok well, like I said I'm no expert and the vid you made seemed to show the bow lifting a lot more than in that new video. I will say this about the new one though..
a) Its on a completely smooth surface.
b) The guy is a bit of a lard arse and probaly weighs more than you and your girlfriend together. Of course you can put pretty much any power outboard on a dingy if you got enough weight at the bow to keep it down
Yes it looks like a great deal, also with Yamaha they measure the HP's at the prop and at the other manufacturers they measure it at the engine am i right?
@ above, ye i am much lighter than him but i haz telescopic throttle thingy on my dingy so that isnt a problem

Well that isn't really true because you cannot put too much weight into a little rubber dingy or it will simply sink anyway. You need to find the correct balance between power and weight. Too much weight will mean the boat will not get up onto the plain. Then there is having too much power which will actually plough the nose of the boat down into the water which means more water resistance so you will not gain any speed. Then there is the weight of the engine on the back aswell. So there are other things that need to be considered too!
On my aluminium boat with the 40HP outboard on the back, the boat is actually ever so slightly overpowered because the boat is so very light. This is not a problem though, because we have power trim on the engine, so with a little switch on the side of the throttle I can actually raise the engine hydraulically, which lifts the boat up onto the plain, reducing water resistance and dramatically increasing the speed. It's like a NOS button!
However, without tilting the engine, you can tell that it is overpowered because when going at full speed, the boat rises up onto the plain and then the front digs into the water a bit, which slows it down and wastes fuel. It all depends on the equipment that you have available. The 40HP outboard I have would be useless for the boat if we did not have the power trim, but because I have that available, it is absolutely perfect for it!
I also have powertrim, but its done by hand.
It has 6 trim positions, and i always have it on the fourth one (tilted up a little). Thats why it doesnt go into plane very fast, and when i go into plane i always go sit in the back for more speed.
Trimming is VERY noticeble on my dads boat, you can gain almost 10kmh with it.
And the rubber dingy will not sink, People+engine+luggage -> it can carry 450 (same as my dads Stingray 180) kg
Me is 60kg ;p + 28kg 5hp engine + 10kg of luggage = ultra speed
The 10hp engine is about 40kg so its no problem.

I don't think you understand me. If you continue adding more and more weight to your boat to balance out more and more power, it will eventually be too heavy and unstable and it will sink. I wasn't talking about a 10HP engine, I was talking about whoever said that you can use any amount of power aslong as you have enough weight, but that won't work because if you want to put a bloody 200HP on the back of your dingy you are going to need loads of ballast in your boat to balance out the weight and power of the engine and it will be overweight and cause your boat to sink. I'm not just talking about your boat I am talking about any small and light boat that has to have a limit on how much power you give it.
Here's a couple of pics of mine.

Ok sorry, now i understand you.
Same.
Well obviously. I was talking about within the limits of the displacement of the hull. I would have thought that was a given in any discussion about boat loading. Everybody knows if you put too much load in a boat it will sink, didn't think that was something that would even need to be said.
Well excuse me for taking what you said exactly how you meant.
Gills can you post a pic of your boat?
doesn't really make hell of alot of difference on the brand, some are more reliable then others - thats a given But budgets can be restrictive... once its not a mercury its grand
as i said 10hp if its you and 1-2 people 15 for an extra person 20 or more would be overkill.
just be greatful that you have a boat, ive the use for a 17 foot but i can use several others if i wanted...
just need good weather... we only get at best 4-5 weeks of fine weather before the digneys go back in the shed and the bigger vessels stay out

A life vest?
Well i haven't been stopped by the cops in 10 years there and i recognize them from miles away so no worries.
