[QUOTE="turbotodd, post: 347752, member: 7376"] All of the 40 jet Yamaha's are considered long shaft (20"). The motor has a "15 inch" leg on it but the foot is longer than a standard prop foot, which makes a short leg into a long shaft motor. As far as I know, there is no such thing as a short shaft jet. At least not with Yamaha. They have to be run high on the transom anyway. Most of the river boats I've mounted them to were 20 3/4" from top to bottom. Some were tunneled but 20 1/2-20 3/4" from top of transom to the top of the tunnel, with the tunnel being about an inch deep and about 18 to 24" wide depending on the model. [/QUOTE]
