Yeah really!
One more comment for anyone who has to make this repair: See the detent holes for up/hold/down? A ball engages with them, pushed by a spring. Don't remove the external bolt containing that spring before lifting the assembly off the transmission! Removing that bolt would let the ball and possibly the spring, fall down inside the transmission. It would be a good idea to just loosen it 1/8 turn, so it will be easy to remove after the assembly is on the workbench.
Likewise, there are two large bolts on top of the assembly that should be loosened just past snug, that attach the lower half of that valve assembly (post#16 item 1) to the cover. I had to re-mount the cover onto the transmission to have something to pull against, removing those bolts, and measured (beam torque wrench) 65 ft lbs to loosen them. So free them up before taking the cover off.
I hope nobody ever has to make this same repair but Hoye says they stock a replica lever assembly because this repair is so common. I was lucky the lever assembly wasn't botched on mine. It only needed the broken spring pin replaced. Yanmar should have had a slot for the hand lever to run in, so the lever couldn't be pulled back too far.
