Evinrude Lightfour – Military Edition?

[ausf233]

Hello all,

I am helping a friend to source information relating to an Evinrude Lightfour in his possession. Unfortunately he hasn’t provided any photos yet however he has advised that there are two ID plates affixed to this outboard.

The first (main) plate contains model and serial number, 4398-00250
The second plate states Bureau of Ships. No. 0-12842

Via the ‘Old Outboards ID Guide’ on Maxrules.com, I’ve been able to obtain a little more detail (1945 9.7hp Evinrude Lightfour, Heavy Duty Long-shaft, Air-borne Reverse). I’ve not been able to find much else on the internet.

Before I go back to him with the above-mentioned, I would like to know what the terms Heavy Duty and Air-borne Reverse actually relate to, and how this outboard differs from a standard Lightfour of the same/similar vintage.

Needless to say, any additional information would also be welcomed.

Thanks & Regards,
Spiro

Your 4398 Military Model is five inches longer and the Heavy Duty description probably refers to the stronger than normal transom clamp and single tube joining the powerhead to the gearcase. Civilian versions had separate exhaust and driveshaft tubes making running in reverse impossible. Air-Borne Reverse could refer to the steering wheel which goes around the powerhead making it easy to spin the motor for reverse thrust.

Check out this PDF file. Lots of good information on the military Light Fours and Zephyrs.

Thank you Mumbles.

I will read the attachment with great interest.

The ‘Heavy Duty’ often refers to the high reduction lower unit with the large prop. This unit is lubricated with oil rather than grease. Mine will manage enough speed to plane my fishing boat.
