Hi all

It seems it’s partly amplified by mounting the motor. If you hold the motor in your hand the noise or vibrations isn’t really noticeable, but as soon as you rest it on something, the noise is amplified through whatever its on. The boat hull being wood coated in fibreglass amplifies it a lot.

Now I have the motor mounted sitting on bubble wrap as it’s the only thing that keeps the noise to a minimum but the motor which I got wrong and is a 900bb torque is very powerful but very quite in terms of when spinning. My only hassle now is how to fix the motor to stop it torque twisting when the props in the water. I had thought of those little rubber mounting things with a threaded section either side of the rubber cushion, then hang the motor rather than mount it.

I will however try the Electronize switching between high and low frequency control as it has that switch on it.

Many thanks for your help.

Don
