The said Lightfour Fire pump and two Champion S1F’s came home with me today.
The model number on the power head’s brass core plug is 932, serial number 00635.
There’s a matching number stamped in the aluminum pump flange, as you can see
in the one photo.
I can “not” find this model number on either online Evinrude model list I had bookmarked.
They both had models listed up to 927 (1933) and no higher in the 900 series.
What year is mine?
Would the later Lightfour motors use the same internal parts, ie., pistons, crank, etc?
Is the round cover the “choking” mechanism? It says “In Starting Hold Down”
“Till Pressure is Developed”
Not sure how the fuel system is all plumbed, but it looks like a strange set up!
Thanks!
Prepare to be boarded!
