Hi xx29l9,

As result of the rather steep propshaft angle, the answer to that question may very well turn out to be: "yes".

Installing too much power will push the bow down (or the stern up) making the boat run very wet and slow, while the motor will draw a lot of amps.

I only just stumbled upon your build, otherwise I'would have warned you (much) earlier.

Going fast with a modelboat requires a propshaft angle that's as shallow as possible.
This means either using a very long shaft, and the motor way up front under the foredeck, or using a flexshaft, which will allow you to run the shaft parallel to the keelline.

My personal objection to using a flexshaft in a semi scale model is the necessity to pull the flexshaft after every day of running the boat, to dry it and re-grease it.
Failing to do so will cause the shaft to rust solid in a matter of weeks...(or days, if you're running in salt water).

Regards, Jan.
