I have a deck boat with a 120 Hp Mercury. I took it out the other day and initially it had plenty of power but after running for ten minutes it lost power and would only go 10 mph. It ran without sputtering or any apparent power but just no power. The throttle cables look like they could be replaced but I took the cover off and tried to increase speed manually to no avail. I am thinking it could be a fuel filter but did not see one in-line. If anyone has any suggestions it would be appreciated. If anyone has a manual for this motor I am in the market for one.<br /><br /><br />Jim <br />golfgod7@juno.com
