Model J175PLEES, can't read serial number sorry, starts fine when cold, when I make a run 10 to 15 mins. stop and start fishing lets say after 15 to 30 mins or so when I try to start it back up it will start and die, start and die. If I keep it in neutral and rev it up it will clean itself out and once I get it in gear and back up on pad it runs fine. I changed spark plugs, still does the same thing. I did notice the last time it happened on Friday, I got up and went back to check the squeeze bulb and it wasn't hard and I had to pump it back up but it still acted up until i reved it back up to clean it out. I just bought it a month ago and it hadn't been started since last Aug before I took it out. I've had it out 3 times already. Like I said it runs fine once it gets going and up on pad??

get rid of the bulb first off as a chamber may be going bad. DO NOT replace with walmart kind get an OMC one. then try again that may be your culprit, if not the next is the check valve in the tank or the gas pump on the vro

Ok, I replaced the fuel bulb, took the boat out this past Saturday. Same symptoms as before. If I start it cold and run it first thing in the morning it's fine. If I shut it off and try to start it again right away it's fine only if it sits for a while it won't go until i get it to "clean out" by reving it up several times then it gets right back up on plane. It seems that it's a presure thing? Is that possible? Oh, and it doesn't miss fire at all up on plane, runs like a striped ape

May want to check the float drop on the VST it could be hanging if you don't know how to do it either take it to the shop or get a shop manual to assist you. The VST is the vapor separator tank that the OMS/VRO plugs into. You may also check your throttle roller position via the thread at the top of the forum.
