What is Latham Stage Three System? You mean Whipple Stage Three?

When I had problem with my mine dieing when shifting, it ended up being a trans cable binding up - which prevented the shift interrupt switch from fulling switching. You can try disconnecting that switch as a trial, but Mercury wants it there - probably to protect the weak NXT transmission. Some people run with the switch disconnected - but it's likely there for a reason.

Yes itís the nxt package.. Neutral to reverse and then dead. No stumble Ö itís now not doing it as often but still doing it. Occasionally it will die in Neutral.

After throwing all kinds of parts at it it's better.. keeping the drives neutral at the dock seems to help to. Livable but have to pay attention If the wind is ripping and have wave action cause if it dies no power steering
