Here is what I am facing. Motor died last April while running full throttle. First time any issue in 10 years. Found to have no spark. Replaced coils, wires, plugs, stator and power pack. Got it back out and it fired up and did low speed fine. When tried to get it up on plane, it bogs down. If I get off the throttle, it wont die. If I stay on throttle it dies. When accelerating, the bulb feels nice and firm. I did discover I can give it just enough squeeze to get the boat up on plane and have to continue pumping it to keep it running. This does not always work smooth, but it has worked. I have rebuilt the carb, replaced fuel filter, diaphragm, fuel lines, and different fuel tank. No luck. While working my way through these different replacements, the new power pack died. Got another one under warranty and it fired up, but still bogs down. Had it to mechanic as well. All electrical is to spec. He is out of ideas. Been through a lot of forums and still looking for help. Any suggestions are greatly appreciated!
