i have a 40 hp nissan im not sure what year it is but it was set up for console steering and its an older motor i think late 80s early 90's i was wondering if someone could give me some info on how i might install a tiller handle on it and if so what i need to buy and how much they cost and if they are even still available (or maybe even how to rig up some kind of make shift tiller handle) its a 40C. thanks.
