The update I referred to solves this issue.
What I was referring to was a case where the bucket went down without input or knowledge of the user while maintaining full thrust which is a worse case event .
It sounds like your talking about a case where after input from the user . was slowing the pwc down to fast which is also not good . I have had no problems with my 2015 IBR and not herd of any reports of problems .
From the injured party :
While under way and under power, a bolt that attaches the braking plate to the control mechanism snapped in half (Please see attached photos) resulting in a full deployment of the "brake plate" while thrust from the jet pump was still being produced. Under normal operation, the throttle is overridden and reduced to near zero when braking is desired. This was not the case being that the "brake plate" essentially activated itself when the bolt broke in half. Not only did it activate itself, but thrust was still being produced resulting in a very aggressive and uncontrolled braking which y :resulted in my flying over the handle bars (Stern Up - Bow Down).
When I flew over the handle bars both my knees impacted the handle bars. This caused bruising (Please see attached photos) and pain in both knees and additionally to my lower back. When I flew over the handle bars, the impact of my knees into the handle bars caused the handle to move all the way forward and crush and dislodge the instrument cluster.
My Honda has a ATTS software operated differential
Its has many sensors and actuators .
When the software gives a command to the actuators the sensors feed back info to the computer verifying that the command was fulfilled which acts as a safety check against the system . If you have some software operated device like IBR that your safety depends on that does not have such checks and balances then a glitch can cause you are someone else to be injured . For that reason with IBR I would not do something like charge up to a dock or a bridge at full throttle and nail the brakes cuz like on a out board using reverse engine thrust to stop you is not a safe thing to do .
