Has any ever made, or had made, a flywheel
for a battery ignition outboard, on a lathe?
I’m just "thinking" at the moment, as this
Rube Goldberg magneto adaption on
my newly acquired 1930 Elto Speedster,
"has to go"!Also, I’m curious as to the inner workings of the
timer for such a motor. Is there a push rod
that works off a lobe on the crankshaft?
So far, I haven’t been able to get enough
parts off to see what my crank looks like.
Photos of the insides of timers would be great!
Thanks!Prepare to be boarded!

I can only think of one ( there are probably more ), but…
contact Chris Scratch, he is the man you are looking for
at least for early Rowboat Motors !

what mine is "suppose" to look like.
I presume the pin on the timing cover is spring
loaded some how, and that’s what the flywheel cam
actuates?I haven’t had time yet to research the mag plate origins.
The points cam I removed appears to be adjustable,
via loosening the set screw in the hub. Not sure what
that piece is from either.Prepare to be boarded!

May 19, 2018 at 8:09 pm #76336Is that a "modern" Mercury flywheel hub they used on that?

seen the top sides of some hubs with 8 holes. Pretty
sure mine has twelve.Prepare to be boarded!

Possibly better performance and the ability to dial in the timing better without having to keep up with a battery box and all that stuff which would allow it to run in no battery enviroments? It sounds like you can adjust the timing via the hub of this motor and that may explain why 12 holes were used on it so even the flywheel could be moved back or forth a bolt or 2 to get timing perfect in respect to where the cam is adjusted to. Not an electronic ignition but pretty cool how they made it adjustable which would allow it to work on a lot of motors. I for one would like to hear it run with that set-up verses the timer box.
I also wonder what year it would have been modified.
Have you tested that condenser on your Stevens meter?? That thing is a monster wonder what its mfd rating is>
Just my thoughts on it.

ps someone in another thread did mention they knew what exact motor this set-up came from but I wonder if it might have been used by the factory to set-up the best timing on motors due to the 12 holes on the flywheel and the adjustable cam. It may have never been intended to run up and down a lake with 12 holes. It could be used on many motors to pinpoint the best timing from slow speed to high speed operation then mass produced. 12 holes gives it a lot of adjustability not 8 not 6 but 12 that’s a lot. I also think of how large that condenser is which also makes me think that it is very very old and one of the first ever used. With that set-up you could run a motor at WOT with different timing settings to see how long they stayed together in respect to one another no battery needed. I’m just thinking out load just crazy thinking so I’m sure someone will shoot me down but it I think its cool. They did test intensively test test their outboard engines back then one bad year and things could go very badly to bad they got away from that.
May 20, 2018 at 2:47 pm #76403Unfortunately, the seller knew nothing of the motor’s
previous history, and just said he "took it in on a trade".I have no clue if you’re "onto" something with the
adjustable timing for testing purposes, but it’s
fun to hear you "think out of the box". I usually can’t
even think "inside the box"!I have not removed the huge condenser yet, but
I plan on seeing if there’s numbers on it, and
I could try testing in on the Stevens.
Thanks for the ideas!Prepare to be boarded!
