plugged high speed jet

[dyancey]

I have a 2000 25hp mercury outboard that appears to have a plugged high speed jet due to gas that had sat to long in the tank. I have cleaned and flushed everything up to the carburator but the engine still bogs down when put into gear. Do I have to remove the carburator from the engine to get to the jet for removal and cleaning? is there another cleaning method that i can try before removing the carburator? thanks

Re: plugged high speed jet

Howdy, DYancey.<br /><br />Bogs when put in gear? Have you verified that both cylinders are running?<br /><br />Check that first. Just short out each plug and see what happens to idle speed. If there is no change that is a dead cylinder.<br /><br />If both are running, then remove, dismantle and carefully clean the carb. <br /><br />You will need a shop manual and a carb overhaul kit. Get them first.<br /><br />If you do have a dead cylinder, check spark to the dead cylinder. Got spark? Run a compression check and let us know what you found.<br /><br />Good luck.
