Hi guys.
I went e-foiling this morning and the problem is fixed! Thx for all your help.
I’m guessing the problem was the motor was slowly spinning backwards when the prop was folded. Thx for all the ideas to try @jakebarnhill1 @Alexandre @Giga. Jake, you are the trouble shooting winner for the prop spinning backwards idea!
I changed the motor settings so the motor brakes when I let go of the trigger. And I maxed out the start up boost. Now it starts up everytime. Now I can up my surfing game!
