SEAFOAM is your friend, remember this. Get you 1 bottle of SEAFOAM(available at most any autoparts store or WAL-MART), 5 gallons of gas, and the proper amount of oil if it's a 2-stroker(yes 4-strokes require de-carboning, even more so than 2-strokers). Mix 1 bottle of the SEAFOAM with the 5 gallons of gas and oil(if needed), and put this in a small gas tank on deck. Unhook your fuel line from the main tank and hook it up to the portable tank with the magic elixir inside. Run engine for 5 minutes on the mix at or below 1500 RPM's(some like to do this with no load on the engine, others with a load on it), let it sit for 15 minutes with the engine off. Repeat this process until you notice a drastic decrease in the amount of smoke that comes out when you re-start it(usually 2 times, but as many as 5 if severely carboned up). There are many methods for doing a de-carb, but this method is regarded as the easiest to do with the least amount of chance of engine damage being done(yes, carbon can damage an engine if it is removed too quickly). Maybe one day I'll do a video of me doing a de-carb the old fashion way ;D(smoke, lot's of smoke).
