Just looked in my “Notes” on my LT-37……….
==============================
1937 Johnson LT-37, 4.2 hp
Serial 269570
Complete, minus one transom screw pad.
T – 60 psi compression
B – 58 psi
Coil, primary .1 ohm, secondary 3.21K ohms
No continuity on the flywheel bakelite distributer
contact, “to ground”.
==========================
The last entry in my notes refers to the “grounding”
system that allows the coil only to “fire” the piston at
Top Dead Center.
If you have to remove the Bakelite plate, be very cautious,
as it could break easy. Mine already had a crack in it, but
it didn’t effect it’s operation.
Prepare to be boarded!
