I have a 200hp oceanpro This is the problem the engine has preformed great no problems. I brought it home and was flushing the engine. When I attempted to do the flush the engine started and ran fine for 5 Min it then started to miss and shut down. It will restart and run and then the same thing happens starts to miss fire and shut down.

welcome to marineengine!

does it miss continually now or just after warm up?

does pumping the primer bulb help?

spark good on all cyls?.....need to check immediately after it shuts down..could ne something heating up and going out.

are you running a fuel/water filter?
 
It ran fine on Sunday this wee

It ran fine on Sunday this week went out for a 5 hr day no problem. Monday I went to do flushout and it would run for 5min and then start misfiring and shut down. I do have a fuel and water filter. If you squeeze the fuel bulb it will correct the problem for 5 more min.
 
sounds like fuel pump is going

sounds like fuel pump is going out or you have developed an air leak in a fuel line.

the primer bulb acts as a manual fuel pump...........the 5 min deal sounds like it is squeezing every bit of fuel from carbs and then starving.......until you pump the bulb.
