From what I've been told the gear reduction is the better option to retain a typical diesel prop and that it gives you a more likely case to keep the one you already have. It allows the motor to spin faster, since its top speed is 5k rpm, while delivering half that speed to the prop which was designed to have its top speed around 2500 rpm or at least cruising speed there. That's my understanding of it.
Can anyone confirm this is accurate and does anyone here use their motor without the gear reduction and simply avoid pushing the motor higher than the 2500 rpm the prop works best at?
Also, is there any efficiency gains by running the motor at the slower rpm vs the higher rpm with the gear reduction?
Lastly, I also read that without a gear reduction you need a linkage of some kind that will help reduce the torque load the motor produces. So going without the gear reduction there is probably another component you will need.
Just my 2 cents and really interested to see if I got it right and learn something with you.
