25 hp Johnson wont stay in gear

[Jim DeVries]

I have a 1978 Johnson 25 hp engine that won't stay in gear at medium or high rpms. I have had the lower unit apart and the gears look in fine condition, the shift rod is adjusted properly. This was a problem I had last year too, so I purchased a used/rebuilt lower unit and the problem is back again with the new lower unit. Any ideas why this would happen again? Could it be the prop? What else might be going on that I haven't figured out yet? Any ideas would be greatly appreciated
