Its seems my splined blower pulleys are odd and never fit the merc splined shafts people have. |

The difference between older and newer splined styles is the offset distance front to back. The older style are toward the back, the newer style are toward the front. I have the newer style on a VI, don't have dims as the boat is in storage though.

The part number I used for the keyed shaft was a Weiand91180. Part is listed for the 144 blower, but it fit my 177 blower. $209 @ Summit.
