The serial number is 4160030 on this particular Sea King. looks like #9186 is the Sea King model and 416 is the Evinrude model designation.
1932 - 1935 4 horse model from the info I am finding.
I'm hoping to locate the lower unit below where it bolts on at the midsection.
I don't know what a shop would charge or who would even be willing to repair the skeg.
I am guessing the lower unit for this model is not going to be an easy find.
This particular lower has no cavitation plate or cutout for water or exhaust tubes. Not sure if all the model 416 Evinrudes were like this or not.
Thanks for aby help.
