bigbuck Posted July 12, 2011 Report Share Posted July 12, 2011 Check your fuel lines to see if there is an issue with venting. Does the primer bulb on the fuel line stay full after you give it a couple of squeezes?? Link to comment Share on other sites More sharing options...
HTHM Posted July 12, 2011 Report Share Posted July 12, 2011 Trying to get it in order for the cure for cancer tourney...hope you's can help The good news is: You won't need the engine for the tourney. I don't know if you were aware but the lake is electric only. The bad news is: I have no idea what to advise you on your engine. Link to comment Share on other sites More sharing options...

DRIFTER_016 Posted July 12, 2011 Report Share Posted July 12, 2011 Could be a few things. First off it could be a fuel problem or an electrical issue. I have a couple of questions: after it dies do you have to pump the primer bulb to get it to restart? Have you checked the fuel filter to see that it is full of fuel when the engine dies? If you have and the filter is empty/bulb needs to be used to reprime the system you either have an air leak before the primer in the line or you have a problem with the fuel pump. If fuel is fine you probably have an electrical issue either an intermittant ignition component or a loose connection somewhere. Check all connections and disconnect and reconnect any bullet connectors. If the problem persists head on over to your local Honda Marine Mechanic and have them look it over for you.

tightline Posted July 13, 2011 Author Report Share Posted July 13, 2011 The bulb does soften up and re priming is necessary...it ran like a dream the last time I had it out until the last day of our trip? Then on the way back to camp this prob started arising?? Thanks HTHM for that news flash, would have been a slow day on the water paddling my 14ftr around Link to comment Share on other sites More sharing options...
fishermccann Posted July 13, 2011 Report Share Posted July 13, 2011 That happened to me and I found out that the fuel filter was semi-pluged the presure when you pump the bulb would force more gas past the obstruction. If the motor will keep going if you continue to pump the bulb then I would bet that is what is wrong. Link to comment Share on other sites More sharing options...
irishfield Posted July 13, 2011 Report Share Posted July 13, 2011 On the same lines don't forget there is a screen over the intake tube in the fuel tank as well that could be clogged or the tube itself has come dislodged and you're sucking air.

tightline Posted September 3, 2011 Author Report Share Posted September 3, 2011 Anybody know where I can find an engine schematic for this motor online without having to buy it for 40 bucks!!! Link to comment Share on other sites More sharing options...
Terry Posted September 3, 2011 Report Share Posted September 3, 2011 when I had the same problem it was where the gas line meets the engine it was sucking a little air if I squeezed the blub real hard I could get some gas to leak out a new connector or a bit of teflon tape solved the problem for me on a honda 5 hp Link to comment Share on other sites More sharing options...

Big Cliff Posted September 4, 2011 Report Share Posted September 4, 2011 That happened to me and I found out that the fuel filter was semi-pluged the presure when you pump the bulb would force more gas past the obstruction. If the motor will keep going if you continue to pump the bulb then I would bet that is what is wrong. Yup, first thing I would do is change the fuel filter based on the fact that it happened to you on a return trip. But it could be as Wayne suggested or an air leak. My bet would be on the fuel filter though. Link to comment Share on other sites More sharing options...
johnnyb Posted September 6, 2011 Report Share Posted September 6, 2011 Just wondering if ethanol could be part of the problem? I've run into similar problems and a bit of stabilizer cleared things up...I know squat about this stuff...but thought that might be worth mentioning Link to comment Share on other sites More sharing options...
dave524 Posted September 6, 2011 Report Share Posted September 6, 2011 Could be as simple as that little O ring in the gas connector to the engine, had much the same symptoms once , that was it. Link to comment Share on other sites More sharing options...
lpu_ofn Posted September 6, 2011 Report Share Posted September 6, 2011 Does it idle/run poorly or roughly? It could be a fuel/air mixture issue. or Bad fuel pump Bad gas Plugged Fuel Filter Plugged or Pinched Fuel Line Major vacuum leak ...... Link to comment Share on other sites More sharing options...
