The dog's paw blocks my view, but that control lever looks like the type that I used to have. Don't these have "snap disconnects" that allow you to pull the handles out of the base when they might be in the way of sailing? With that feature you should be able to have them mounted higher, right?
The control is for a yanmar 3gmd. It is the throttle/gear selector on one lever (fwd/neutral/reverse). My controls do not disconnect, but I understand there are newer types that have controls that disconnect or fold away- that would work better.
