thoughts on adding a Permanent wiring harness for trolling motor/running lights.

I have a riot mako versa 10' – I recently set it up with an trolling motor – fast and dirty – direct to the battery.

The OEM leads on the motor are short enough that the battery has to go behind the seat – this throws off the trim.

The Kayak is designed with a spot at the bow to mount a battery.

My thought is – install a 50A marine grade disconnect onto the hull at the bow, fish 6ga marine wire through the hull (future proofing if i ever go to a larger motor), with a disconnect at the stern – and cut the spring clamps off the motor leads and replace with the marine 2pole plug.

I'd wire in an appropriately sized breaker/fuse, and possibly even a switch panel for some addon running lights for those nights when i'm chasing crappies.

The motor i've got right now is 28lb thrust – 30 amps draw. works great on a 100ah Marine deep cycle.

Minn Kota specifically says to NOT extend the leads – but if its only drawing 30 amps at peak, am I really going to see that much voltage drop with an additional 8' of 6ga wire and two disconnects? If i have to I could put a wire gland at the bow – and run the wire direct to the battery terminals – but for convenience I'd like to have the battery easily removable.
