Regarding electric v motorised outboards, I wonder how long it will be before all electric outboards have (like strimmers such) clip on/clip off lithium batteries. There are some out there I know but in many cases we are talking about a couple of grand.
This leaves the financially considerate with two options when it comes to weight. The weight of a conventional ontboard compared to that of a much MUCH cheaper 'just the motor' electric outboard, along with a much MUCH cheaper lead acid battery to go with it.
A sort of quid pro quo, as it seems to balance out.
