Picture of it running showing my test setup.
Here is some video of it running.
While the engine was running at idle I shifted the motor into both forward and reverse gear. All seemed to work fine there. After the engine run I drained my test tank. The lower unit was covered in exhaust goop. Gear box was ok. Picture of lower unit after test run.
With the test run complete its time to finish up the trim details and start putting all the cowling parts back on the motor.
