I wish I had better data on this test. It felt like RPM was a lot slower under water. However my amp meter only showed 20amps at full throttle in the water. Leads me to believe that there is room for improvement with different props. And then there is the salt water which may have shorted some windings if there were little cracks in the copper insulation of the stator windings. That could explain reduction in power too. Lot’s of variables
