[64'Cherokee]

I have a 64' Evinrude 40hp outboard. Ran great all summer. It developed a problem late in the summer when running at full throttle. Half throttle runs smooth, push it to full throttle, and it appears to pop out of gear. When you throttle down half way, it runs fine again. I did check the seals in the lower unit, they're ok. Haven't looked at anything else yet. Suggestions on where I should start ?
