I'm no closer to understanding whether my 72 volt/3 kW motor with its 20aH lithium ion battery is likely to kill me in a boat and what I can do to...
Going back to air lubrication, I'd imagine the flat water model testing has been more successful than the real world because the planing surface...
I think I'm going to get a pair of big rubber gloves with gauntlets for plugging and unplugging the battery, and crack on.
I'm building a 72 volt electric outboard using commonly available 72 volt moped/ escooter battery, motor and controller. I have read in various...
Does an electric motor produce its max torque at its rated sustained RPM? This would be 3000w at 4900 rpm. The seller quotes two rpm figures...
I'm converting an old Suzuki DT4 2 stroke outboard to electric. I bought the engine(s) (2 of them non runners for less than I later sold the power...

Ps. When I say 'rotting' in gardens, I mean it metaphorically. That's the whole problem with them. They aren't rotting!
I love the propulsion system on the plywood canoe. I have an aluminium hardtail mountain bike frame behind my shed with a cracked headtube that I...
Hi, As part of a small electric boat build, I am electrifying a 4 hp 2 stroke outboard with a 6kw ebike motor. It's an easy way to upcycle an...
