I have a 2003 Mercury 3.3 HP outboard that I bought from someone off craigslist. The telltale was clogged which I fixed and the carburetor looks brand new. I had a tech fix the clogged telltale and he didn't notice anything else wrong with the engine.

When I took the engine out on the water after idling for like a good 5-10 minutes. It works fine at low speeds but when I increase the throttle the engine hesitates and slowly dies out. Now if I play with choke and throttle I can get it to go very fast but its like a careful dance.

Any idea what is causing this? I am moving and want to sell it but I refuse to sell something that might not be operating properly. What is also the best oil and ratio for this engine?

Clean the carb.

If the pee tube plugs up again stick a wire in it, or blow compressed air through it.
