Maybe he just got himself into a weird situation.
Also a little more experience might help. Outboards didn't even have shut down lanyards back in the day.
And as for as the throttle going back to idle after release, I don't remember seeing that. Once I set my throtttle it's set and the boat will go 20 miles or more like that. I also set the autopilot
The main engine
on my boat is an outboard. It's a 2011 Mercury
5hp 4 stroke
. I lost
the lanyard maybe 7 years ago and have a piece of leech line holding the shutoff out........
I do have to remember to check it (retighten) every once in a while though when the engine
refuses to start for no good reason!
I do have one quick story though somewhat similar. I was out on my new used boat
just before I went into the military. It was about 45 degrees and water
temp lower. It was flat calm. I have the boat just under plan (16' scow 40 Johnson with tiller)
So I went and stood on the bow..........until the boat appeared to start to turn at which time I looked back just before the motor slammed as for over as possible passed 90 degrees! At the same time, I jumped for the center of the boat
I made it and the boat spun otherwise I may have been drowned or run over with the boat. Water
temp was 40 max and I was a couple miles off shore alone with lots of cotton clothes on and no PFD
