Chris is the expert on these, but I have some familiarity with them. It is an electric start outboard – the flywheel is replaced by the rotating mass of the electric motor/starter/generator. I’m sure somebody will point you to the threads that have pics. The ammeter displays the current generated while it’s running, to keep the battery fully charged. The flywheel magneto/coils/points system is replaced with a battery driven coil/points system.
February 8, 2017 at 7:31 pm #52655It functions as an electric motor below 1,500 RPM and a RPM dependent switch turns it into a generator around 1,700 RPM. If you have a long no wake zone to navigate you better have a BIG battery or two. With a battery ignition when the battery is dead, the motor is dead. This 12 volt electric starter was offered on several models of Evinrude, Elto and Johnson. Evinrude also offered it as a trolling motor. . . 😆
February 8, 2017 at 10:12 pm #52667Thanks for the replies. It sounds like the generator spins the motor over
for starting and charging once running, which I could have envisioned.
However, it being an electric outboard below 1500 rpm’s I never fathomed!
Are the pistons moving while operating as an electric trolling motor?
If not, what kind of an affair disengages the pistons / engine from the
electric motor? Very interesting photos.
Thanks!Prepare to be boarded!

February 9, 2017 at 1:22 am #52675Yes, the whole internal rotating mass is in play. The port side cylinders have a compression release, so there’s that. But it still is rolling the starboard side cylinders over compression.

the "All Electric" motor batteries lasting 8 hours though.
I wonder how many of those electric start Speeditwins, etc.,
survive?Prepare to be boarded!
February 9, 2017 at 4:16 am #52687Wow! I’ve never seen one of these! Awesome! Garry, you sir are a living encyclopedia of outboards! Thank you for sharing your vast knowledge! I ALWAYS enjoy reading whatever you post! I can always count on learning something new whenever you post!
Thank you sir, you are truly a treasure!
