93' Johnson 150

[Nottus62]

Background: (93' Johnson 150hp on Nitro 180TF) boat sat with sta-bil in gas for about two years. Carbs all gunked up...then rebuilt the carbs, and ran sea-foam in gas to clean it out...replaced the spark plugs. Boat runs fine in the driveway (with hose hooked up to it)...get to lake and runs at idle just fine, in nuetral she runs fine, but in gear, cannot get on plane...just plows. I replaced the fuel line to the motor and took her out today...idle and neutral runs fine...got on plane for about 3 mins, but died off and cannot get back on plane...any thoughts?

Probably still have plugged jets or p***ages in carbs, might try to run on a portable gas tank with the new fuel hose to see if problem is at motor or a restriction in boat fuel system.
