evinrude silver star series 1991 150 hp will not stay running

model #j150exeis serial# Q 02987277 . i got this motor and boat 3 months ago with 10 hours on total rebuild . it starts hard , sometimes 1 minute of spinning over before starting .lately it will start alot better within 30secs , after warmup 3 secs . it seems to run good , but later it will not stay running .it will run for 20 - 30 secs and skip and stall . it will start right up again immediately and repeat . last time out i took it home and flushed it with fresh water and when it started it ran for 10 secs sped up 1000 rpm by itself and stalled . it took right off running again off the key but repeated the problem . its a bummer having a boat you cannot trust to fish out of . if you can help i would really be appreciative . thanks

Contact the rebuilder, if he won't help then take it to a trained OMC/BRP tech there are too many variables with these motors.

Champ, not doubting you, but what kind of variable are you talking about? Curious minds want to know. http://xs-s.com/zf/images/smile/emthup.gif

Ignition, fuel system, etc. parts ain't cheap, he could toss a bunch of parts at it and still not fix the problem. I'd have the rebuilder check it out, if he was worth a flip he should do this for free. http://xs-s.com/zf/images/smile/emthup.gif

i got the boat and motor after rebuild and mechanic would not honor warranty . i am on fixed income , would like ideas on fixing it . i can do the repair , just not familiar with outboards . if it was small block chev would not be problem

Did you get a receipt from the rebuilder? Did it say anything about a warrenty? I would go after his azz and get a refund.
