Looks like a fun little boat! The ESC in your motor has been designed and paired with that prop to perform reliably across a wide range of applications with regard to loading and power consumption. With your application, you might be able to get away with it being a light displacement, but all others should be warned that when swapping out for a larger diameter higher pitch prop, you run a serious risk of damaging your motor’s ESC, or at least triggering error codes/modes. Also that 1917 prop was designed for the 1003 model Torqeedo which incorporates a gear reduction which is partly why it is able to swing such a large aggressive prop. A better comparison to your motor would be the 1103 which is brushless direct design like yours. If you compare the specs of that models prop, you’ll find it is similar in diameter and pitch to your stock prop. In short, anyone considering a swap like this should use a shunt or a clamp meter to measure Amp draw while under load to make sure you are not exceeding the manufacturers stated Max Amp draw.
I know the Torqeedo motor has an overload cutoff so if you get tangled in weeds the motor will spin almost like a clutch slipping. I don't know if the Epropulsion has a similar feature. If it does you may trip that cct by using a too high of a pitch and larger diameter prop. So just watch for that when you test it.
The epropulsion Spirit has a safety system so if the prop gets stuck no damage will result. I haven't tested this set up much but need to get back to it.
Thank you for sharing this! It's something I've been curious about on my epropulsion. Let us know how it's going and if you think there's any improvement in efficiency or performance. Cheers
It was a fun experiment. There was a little bit more push, maybe a slight bit more speed, but nothing too substantial on the first use or two. I haven't tried it on different boats under different conditions though. Thanks for your comments.
Very cool that the new prop fits perfect. Look forward to your report on the performance.

Subscribed and waiting for the results on the water
Can you fit the torqeedo 3 blade prop and show us the difference?
So what is the experience?
Well, it works fine. Makes a bigger wake and might have a little more push. No substantial difference in speed or efficiency.
Curious on the performance difference....thanks for post it.
Perhaps next summer I can compare the two with hard data. Thanks for your comments.
Good stuff thank you !
Thanks! Fun test.
