Genichi Kawakami was a 1933 student from Takachiho school of commerce and in June 1938 started with the company and managed to toil his way to administrator of the musical instruments plant and from that position to the general administrator. By the age of 37 in 1949 he became the factories president and this was to be a splendid changing moment in the objectives of this company. At this instant the organization was growing well and Genichi was determined to start to find many other products and foreign markets that the company to branch into. After studying a lot of products to start planning and manufacturing from darning apparatus to auto parts and after market items he determined that motorbikes would be the marketplace to chase. He together with certain of his supervisers and designers went to many motorbike factories right through Europe and America on information gathering missions previous to starting up a motorbike production factory to churn out their own apparatus. The original model to be built was in 1954 a 125cc contraption named the YAI and nick named the Akatombo which after translated says the red dragonfly. This was painstakingly tested plus being put on on a 11,500km journey to be sure that the engine was dependable and strong. The same year it was made it was put in Japan’s motorbike racing championships and came first above established producers. This contraption proved all the rage and the factory at once began production on a better engine a 175cc motorbike which would be called the YCI.
Genichi was single-minded to contiue on rapidly and in 1959 entered a Japanese built motorbike in a grand prix contest in Catalina in the US in which it came in an incredible sixth. Straight away he used this accomplishment by importing motorcycles using a agent to the American and European marketplaces. The motorbike proved a victory and he extended into the outboard motors market in 1961 looking to deliver both yamaha outboards and construct boats with recent plastics technologies including fiberglass. Not long following this venturing into the marine sector both a vessel the CAT-21 and Yamahas original outboard engine the P-7 were made and the company is nowadays one of the largest motor boat and outboard motors producers in the market nowadays.Information on all outboard motors for sale can be found at the authors site yamaha outboards.

I would highly recommend getting yourself a service manual. It'll save you litterally $ thousands over a couple-three years.
I don't know the '03 yammy in particular but here's some basics on outboard carburetors.
Outboards are particularly sensitive to dirty carbs, but they aren't that hard to clean or keep clean. They are surprisingly simple devices, unlike like the automotive carbs you used to see on cars.
Thing about aerosol carb cleaner is that, anything sprayed through the carb of a running engine goes right past the orfices and tiny passages that need cleaning straight through into the cylinders, where it does what its designed to do: strip oil off of metal surfaces.....not something you want in your combustion chamber.
I use chemtool B-12. soak all metal parts in it overnight, but be advised a lot of plastics will dissolve in it, and it's not so good for rubber, either.
There is probably a recommended special tool for removing the jets from the carb for cleaning, but if you spray aerosol carb cleaner liberally into every nook and cranny, and if they aren't too far gone, you can probably get it clean without taking the jets out. course there's always the chance that you'll have to go back and re-do 'em. I used my dremel to fabricate the tool for my evinrude, from a screwdriver. You'd need the manual for a description or picture of the yammy tool.
It's not really reasonable to expect an additive to clean a dirty carburetor, but there's a couple products that will keep 'em clean.
I add an ounce of seafoam per gallon of gas to my tanks, haven't had a problem since I started with that. Course if I let the motor sit for more than a couple months (rare), I usually clean the carbs just on general principle (that's how easy it is).
"Stabil" also comes highly recommended.
