My 1990 115ETLD came with a 21" prop with one of those centres designed to protect lower end by breaking away if you hit something.<br />I bought a Yamaha factory 19" prop. When I went to put it on, it didn't slide all the way into the lower end housing and I was missing a spacer between the prop and the nut and washer on the end of the spindle. I bought the spacer and it is grooved to fit the splines of the spindle, but there is no room left on the spindle for the splines to engage with the spacer. At the housing end there is a three step spacer that is keeping the prop from going all the way into the housing. If I take this spacer off, the prop fits properly and there is now room for the new spacer after the washer and nut.<br />According to the Yamaha web site though, I am supposed to use both spacers.<br />What should I do?
