The test is if the magneto makes a spark.
Its the speed that the magnet passes over
the coil that intensifies the spark not how
strong the magnet is. I only had 1 motor
(1922 Evinrude) where the magnet was so
week it wouldn’t produce any spark at all.
I spent a considerable amount for the
magnetizer that I have. I was sure that
by recharging the magnets I would be able
to just spin the flywheel with my hand to
start some of my smaller motors. As time
went on it became clear that if there is
enough magnetism to produce a spark
increasing the magnetism wont make it any
stronger as demonstrated in the video.
After WW-II motors have permanent
magnets. Attempting to recharge them will
destroy them and they cant be repaired.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
