Need to update this, looking at cheap outboards and expanding the battery bank to power duel outboards.
Single 1.8 kW motor is fine for:
- downstream cruising
- canals
- sheltered water
Not fine for:
- crosswinds
- tide
- emergency manoeuvres
Dual 1.8 kW motors (3.6 kW total)
This is where it starts to make a bit of sense, with comfortable 3–4 knots through water
- Some control
- Redundancy
- Differential thrust steering (huge win)
Stern platform + outboards solves several problems at once:
Clean water flow to the props, adjustable motor height, easy removal for tender use and redundancy (with twin). Prop centre line is likely impossible to get below keel depth. So seting them wide is better as not tucked in, best not to hug the centre line and place outboards far enough apart that each prop gets clean water flow. This improves steering when running electric-only.
