A buddy of mine has an old Tohastu 18hp. Its an M18A and I believe it’s a 1981 model. The prop it has looks pretty damaged so he wants to get a new one. Issue I see is that the motor has a smooth shaft and all the props that I see for sale on boats.net and through tohatsu for the M18 2 stroke all have splines. Can these props still be found? Any help appreciated.
