Approximately what speed would a 16 Allison be going running a 28 chopper, 1.8 gear ratio and turning 5500 rpm? Was testing a boat but the speedo wasn't working.

74 with 9 percent slip 71 with 12 percent. Those numbers are from mercuryracing.com

Cool. My seat of the pants estimate was 70-75 but my passenger was doubting that he was thinking 65. Thanks

It should be around there, but slip changes it.
