Gearbox serial

34903 is coming up as a camshaft serial number. What is your engine serial number?

Engine serial number is 5848057. See picture of gearbox indicating s/n 34903.

Looking in the Parts Catalog and searching for Gearbox Part Number 887703 and referring to all the attached notes shows...

Version 2 Gearbox.  (Fixed Pitch Prop Shaft.)
With Clutch.
2.43: 1 Gears.
Wide Dog-Gears.
S.N is Before The Oil Spray Nozzel was added.

OK, found it this time, and Gearbox Assy. 887703 sn:34903 is original to your engine 5648057

Thank you, Admin and Bill for the feedback. It is much appreciated. 

Could you check this serial number also? P/N 888560  S/N 20918

I would like to know if I can replace S/N 34903 with S/N 20918.

Thanks in advance for your time.
