I have a feeling what you will run into on the GST conversion is issues with building diffs that will hold up to that kind of power.
Get us some vids of the boat and the GST if you can. Can you actually get a prop for the boat large enough to make use of the torque this thing can make?
Unsprung weight. Let's talk about that. A Motor in each wheel setup would have a center of gravity that would be unbeatable. The bearings in this motor are HUGE and appear to be up to a good amount of abuse. Not only that, the power isn't even being transferred through the output shaft anymore. The output shafts new job would be to just hold everything and keep it spinning true. It's now an "axle shaft" more or less.
With advanced Electronics and programming, we will have independant traction control. A slipperential would be a matter of programming. So would "diff slip".
Diff slip would be a matter of limiting amp draw based on steering angle. An ESC controlling this would become more of a PLC.
I really look for this to become a reality with full scale on road Electric Cars in the future.
The drive motors will be sensor based to smooth things out and completely eliminate cogging and erratic behavior.
No drive train! Can there be a more efficient way? How about one that's going to hold up longer? About the only "wear item" in this is the bearings in the motor.
