I have a 2006 johnson 90hp that I have to keep the bulb pumped for it to get on plane and get it up to full speed. It started doing this a couple of weeks ago, but wasn't nearly as bad then, and it has gotten progressively worse since. When I give it throttle, it will start to go and then once I hit a certain RPM it will just bog down like it is starved for fuel (which I'm pretty sure it is) if I give it any more throttle. If I have someone sit there and pump the bulb it runs great as it should. I put a new bulb, line and tank fitting on it last night, as well as bypassed the water/fuel separator and it ran no differently. I have looked over the whole motor multiple times, and I don't see gas leaking from anywhere and the bulb gets hard when the motor isn't running, like it should. I am thinking the diaphragm in the VRO pump might be torn and that it needs to be rebuilt, does this sound like it could be my issue? Any advice or other things to check would be greatly appreciated. Thanks.
