Guest Posted September 29, 2003 Share Posted September 29, 2003 I got a problem with a 2002 25hp 2 cycle Mercury. It starts and runs fine at slow speeds but once I give it full throttle it will cut out when I'm cruising along. Almost like I'm letting off on the tiller but I'm not. Help!

0 upnorth Posted September 29, 2003 Share Posted September 29, 2003 Is the primer bulb collapsing? If it is your tank is not breathing right. Link to comment Share on other sites More sharing options...
0 Try Too Fish Posted September 29, 2003 Share Posted September 29, 2003 Have you tried hitting the choke when it starts to stall? If that helps it could be the jet is too lean for the cooler weather! ------------------Try Too FishForced Too Work!! Link to comment Share on other sites More sharing options...
0 fivebucks Posted September 29, 2003 Share Posted September 29, 2003 I had similar problem with my Merc. 2 years ago and it was the fuel line leaking a little air. Like Upnorth said, check the bulb to see that it remains hard, if not it could be an air leak. Link to comment Share on other sites More sharing options...
0 Steve Bakken Posted September 30, 2003 Share Posted September 30, 2003 How are the clamps on your fuel line hose. Sometimes the rubber deteriorates under the clamps and they have to be retightened. If they're the crimp style and your rubber is bad, cut them off and put on a regular hose clamp.------------------Steve @ www.bakkensboatshop.com Link to comment Share on other sites More sharing options...
0 Surface Tension Posted September 30, 2003 Share Posted September 30, 2003 Very good suggestions. Does the motor come up to full speed/RPM then die or does it just bog as soon as you give it throttle? Link to comment Share on other sites More sharing options...
