"I have a 71 125hp electric shift ob. I have checked compression and its 120 on all four cyl. I put new plugs in and replaced both carbs. When I get to wot, it is okay for about 2 minutes, then it starts bucking or cutting out like a major miss. So much so as to cause the engine head to jerk. I have been dealing with this since last year. I can't seem to find a decent outboard mechanic in this town (Grass Valley,Ca.) If I run it at about half the rpms it runs fine. I don't have a tach and I hear it takes a special kind. Today I took the fuel pump off and put another one on from a 73 135hp I blew a piston in. I knew that pump was good before frying the piston. my first question is this. Will a bad fuel pump cause my motor to buck like that? Second when I took the old pump off I could blow through the black plastic fitting on the pump its self and I couldn't blow through the black one on the pump I installed. What do you all think? Sorry this is sooo long. I'm taking it to Bullards Bar this weekend. I figure if I get lucky the pump was the problem. If not I think I will just do my best to blow the sob up!!!!!!!
Thanks Luana"
