I used a big handle from a socket wrench to put force on the end of the cam rod that exits the shaft housing at the upper end, near the engine. Plunk. It dropped another inch. That seated the cam shaft one notch lower, to the true reverse position. At that point I tightened the cam rod clamp and all the gears were working again.
I hope it works as well when I turn the power on, some time tomorrow.
I see, I think
When you get it on the boat, suggest you put the power to it very easily and slowly. If it stutters or jumps out of gear more adjustment may be necessary.
