15 spline prop.

[ronward]

Could someone tell me what motors use a 15 spline prop shaf?. I have a nice SS prop with no idea what it fits.

Measure the diameter of the hub. 4-3/4 hubs fit V6 outboards and Sterndrives. 4-1/4 hubs fit smaller outboards. Now look up a modular hub listing. They usually say what the spline count is. With that and the hub size, you ill get an idea what it will fit.

BTW - Hopefully it is a modular hub. That makes it easier to transform it to another bran of motor.

Force and Mercury use 15 spline props. SOME OMC use 15 spline, some use 13 spline. AND, I think some of the foreign makes use 15 spline. The larger Suzuki do use 13 spline.

So, you can not tell what engine the prop is to unless you cross-reference the numbers on the hub with prop charts.
