Several weeks ago we changed back to 1 motor. And went out to the dam for testing.
Had to cut the transom / motor mount down so the cavitation plate would be below the bottom of the V-Bottom. There is less boat draft at rest, but with the extra 100mm cut out of the motor mount to get is low enough, bring the motor about the same height to the water level as the 2 motors, mounted higher, but weighing down deeper draft.
I need more buoyancy, to reduce the draft.
We tested all 3 props on this single motor and boat configuration.No significant difference with the 3 different props.
The first column is speed,km/hr, then under each prop size is the current (amps) at that given speed. Of course my measurement reading is probably not all that accurate, but gives an idea of what is happening.
