I have a 2002 merc 75 hp. Last week i was out a couple of times and it did something weird. The first time I was on my way in for the day and the power just cut in half. I was running about 5k rpms and it cut down to just over 2. <br /><br />Then a couple days later I went back out to test it out and find out what was wrong and it did it again and was also leaking gas down the housing. I checked and the fuel line was not cracked or leaking. <br /><br />I called a boat mechanic who said that the float in the carb was probably sticking and the carbs need to be removed and cleaned. He said he could do this, but couldn't get to it til next week... I am in a tourney this weekend and was thinking about trying to do it myself, how difficult would something like this be for a realative beginner.
