[QUOTE="ckr74, post: 491256, member: 3623"] I need some guidance on my 1985 Johnson 35hp outboard. This problem has been ongoing for a couple of years but I want to fix it before winter crappie fishing this year. The problem is that it bogs down at wot. I've rebuilt the carb, replaced fuel pump,and changed ALL the fuel lines. It still runs at low to med. throttle but if you open it up it runs lean. It still gets me where I need to go but it's annoying. Squeezing the primer bulb helps. I'm thinking that maybe the crank seals are bad and the crankcase pressure (pulses) are too weak for the fuel pump to deliver enough fuel at wot. Am I on the right track here? I've tried most everything. Thanks! [/QUOTE]
