Hi, I’m new to the forum and had some questions about by 1986 evinrude 140 hp vro. I bought the boat 3 years ago and have always fought the problem of getting the boat on plane. The Boat idles fine, but when you try to get on plane and push the throttle wide open it bogs and dies. Some times you can Slowly advanced the throttle and get the boat to pop out of the water but other times it will kill the engine. When the boat does get on plane it seems to hesitate and then launch out of the water or hesitate and kills the engine. I have replaced all the fuel line, gone through the carburetors And rebuilt them, replaced the ignition coils, replace the spark plug cables and the spark plugs,And most recently I’ve replaced the VRO pump with a fuel pump and premix my gas. I’ve been thinking it might be a timing issue but I’m not for sure, any help would be greatly appreciated. Thanks!
