First a bit about myself,
I am a 70 year old retired Dutch chap that lives in Wales (UK) 500metres from the sea.
Logically in my opinion I wanted to do something on the water that is doable so the kayak was the plan, but as an engineer of sorts it had to be motorised, hence the 70131 12kw.
I have been out on the water a few times for short trial runs. At first with a 5 kW controller meant for scooters and such but it’s not as free running as it was and on land the motor runs hot quickly and than it failed on me…
I have now compiled a new plan with an ESC ( [T-Motor Flame 80A HV PRO OPTO ESC Speed Controller 6-12S / RC Drone Quadcopter) I bought once second hand and that works with relay for reverse etc. (I now have a new esc on order that has built-in reverse)
So the question for someone with experience on these motors is: what can the reason be for the prop shaft to run stiff after less that an hour running over about 5 months time. Is it ingress of seawater?
And what type of seals are used in these motors? Can I give it an overhaul?
Looking forward to any advice
Happy water fun times
