Late last boating season my motor would lose its prime when running it at full throttle. It would continue to run fine if you had someone pump the primer bulb on occasion. I thought the primer bulb was the culprit so I changed that, but it didn't help any. Would fuel filter or fuel pump possibly be the problem? I haven't looked much, but I'm not 100% sure where the filter or electric fuel pump is located.
Thanks,
Brad
