Lost the prop off my 89 johnson gt 150. Bought a used prop from boat shop it is a 14 1/4x24. Owner of shop said it would fit. Got home put it on and i have a good amount of splines showing and it rubs the case. Am i missing some peices besides just a washer and nut off the front? should there be a washer of some sort in the back? the shaft it tapered so i wouldnt think it would have a washer. prop also have some up and down slack in back. Is this just not the right prop? did i get took? thanks any help would great
