My six cylinder, 90 mercury runs great at low speeds, it bogs out or misses at high speeds.

Could be that you need to do a decarb,and check your fuel lines from the tank to the carbs.<br />Does the bulb get soft? and are the plugs clean?

thanks!<br />I have changed the spark plugs, and pulled the hose off and checked the fuel pump. so the problem must be in one of the carborators, possibly a float?
