Changed the mechanical fuel pump, took it out and it ran absolutely amazing for almost three hours then died on me again, could start it right up but as soon as I'd put it into gear and gave it fuel it would die. Put carb cleaner in the carb got it fired up and it trash amazing again so took it...
The hoses were replaced two years ago with Trident hoses and look very good no sign of issue there. Think it's time to take the carburetor apart to see if there's gunk in the accelerator pump or if the float is sticking.
Spark is on point, no issue there, I know it's a fuel issue all lines are cleared no clogs no pressure build up in the tank. Just not figuring out why it'll run so amazing for over an hour then just suddenly die. Aside from taking the carburetor apart or the fuel pump I'm not seeming to figure...
Took the boat out today after changing the water fuel separator and the fuel filter, cleaned tank and ask the lines, ran amazing for about an hour and a half no issues could idle throttle down and back up with ease and then it started not responding to throttle and would die however would for...
Yes got plenty of spark, changed out the fuel filter and water separator today, not getting any fuel now, wondering if the mechanical pump failed, any suggestions on how to test before I buy a new one.
Looks like mine has a mechanical pump located on the starboard side of the motor, I do have electric wires running to the tank, could there very well be a fuel pump in the tank as well?
Checked for spark, we're good there, changed the water fuel separator today was full of water, now it won't start at all not getting any fuel pressure.
Grub thank you,
Everything is brand new, plugs, wires, rotor, cap, ignition module etc. It only fails and stalls under load and it takes 40 minutes for it to do it. Wait 20 minutes fires right up can get another 40 minute run then does it again.
Gas in the fuel filter looks fine, I haven't checked the ani siphon valve to be honest not exactly sure where it is located on this boat (1979 glasplay 19' runabout). When I filled with ethanol free fuel like I always do, I got fuel spill out of the tank vent.
I have a 3.0 Mercruiser 140 hp runs fantastic on muffs without issue, once I get it in the water and under load it runs great for about 40 minutes then stalls out, I can get it to restart after about 29 minutes can run it wot for 40 minutes then stalls out. All new electrical, carb rebuild...
