i have a 69 merc 650 lightning ignition. 65hp. The boat starts great but idles a little rough. Once it gets down to idling rpms it want to kick and kill the motor. But if i put it in gear before it dies and give it throttle it runs nice and smooth. But it won't go over 6mph. I checked my linkage and i'm getting full movement. Even though the throttle is in the wide open position it stays at the same rpm and speed. I've ran sea foam carb cleaner through it and also just replaced the seals in the lower unit. The shifting mechanism is working fine. It engages both gears as well as neutral. So i don't think that is an issue. I was wondering if there is something i'm missing. Please help me cause i want to get this motor to full throttle. Also when i switch the motor to reverse i have plenty of power. Revs like it should but just not forward??????
