cplummer Posted September 4, 2018 Report Share Posted September 4, 2018 I have a 25 hp 2 stroke mercury outboard. Went out this morning got on lake then she wouldn't restart...it ran with choke on but it wouldn't run. I squeezed the gas bulb and it sounded like air and gas bubbling. The bulb never got hard at all. Any suggestions what i shoild be checking? Thanks Cliff Link to comment Share on other sites More sharing options...

canadianfcat Posted September 4, 2018 Report Share Posted September 4, 2018 Check simple things fist.. air vent open as to not create a vacuum ... make sure hose is connected to both tank and motor all the way . Link to comment Share on other sites More sharing options...
kgm Posted September 4, 2018 Report Share Posted September 4, 2018 Check your fuel hose connection at the motor. I had this problem with my trolling motor, would hear air bubbles in the fuel tank when pumping the ball, and motor would not start. It’s likely sucking air in around the fitting. Nice simple and cheap fix if this is the problem Link to comment Share on other sites More sharing options...
deetch Posted September 4, 2018 Report Share Posted September 4, 2018 Borrow a buddies tank and line and try it. If it works than add your tank with the borrowed line and so on till you eliminate the issue Link to comment Share on other sites More sharing options...

Chrisb Posted September 5, 2018 Report Share Posted September 5, 2018 Can we assume that there was gas in the tank? Always check the obvious first. Link to comment Share on other sites More sharing options...
teedee Posted September 5, 2018 Report Share Posted September 5, 2018 sounds like the vent was closed or u have a air leak in one of ur connections or hose. check all the clamps . td Link to comment Share on other sites More sharing options...
mooseslayer Posted September 5, 2018 Report Share Posted September 5, 2018 just replaced one end of hose at my tank for my 25 Yamaha and it never wanted to fit tight so I put a zip-tie on it and working great now. It sounded like sucking air as well. The old end had some rubber damage around the ball bearing seat. Link to comment Share on other sites More sharing options...

There is a little red pin i pushed it up and down a few times.. It's on the top of the carb.. I am guessing that what it's for? Link to comment Share on other sites More sharing options...
fishingking Posted September 6, 2018 Report Share Posted September 6, 2018 If u see it leaking from where the bowl attaches to the carb u may have pushed the rubber gasket outta the groove it sits in between .u take screw out the bottom of bowl ,drop bowl down and run your finger around pushing the gasket back into place then ,put bowl back on but don't over tighten screw as it will cause it to leak again.then try squeeze the ball and check for a leak and make sure ball gets hard . sometimes high test fuel causes rubber gasket to expand out of position .I've seen this twice now .once we had to boil a gasket to shrink it back to size to fit .good luck with whatever it is Link to comment Share on other sites More sharing options...
cplummer Posted September 6, 2018 Author Report Share Posted September 6, 2018 This motor has under 50 hours on it.. Old guy bought boat and never used it..

Gil Posted September 6, 2018 Report Share Posted September 6, 2018 Cliff, if it sat a lot you may have gum in the float bowl(s) and main gets! A good cleaning and some Seafoam and u should be good to go!!! Link to comment Share on other sites More sharing options...
penetrator Posted September 7, 2018 Report Share Posted September 7, 2018 Always check the easy stuff first, 2 stroke's love to eat spark plugs, if you are squeezing the bulb and gas is coming out the carb's overflow sounds like it getting fuel. if it ran a short bit and died could be the fuel diaphragm. but check the plugs first.
