Used driveshaft source for Johnson 40EL73D?

Post by kmercury » Sat Mar 24, 2012 10:20 am

I have a 1973 Johnson 40hp I need to convert to a short shaft. I am having a hard time tracking down a used drive saft... any thoughts?

You can try for a new part, their web site has enough info that you can figure out the parts you need and then order them. I would suggest from my and Roberta Hegy's experiences with Mercury OB drive shafts (corrosion), that a new or new old stock shaft is worth the money. A used one may be available at the Outboard Exchange in Waterford, CT, (google them for their web site) and lots of used OB parts. A new driveshaft may be available on Ebay, very likely found at places like and Sea-Way Marine in Seattle. I needed a particular long drive shaft for a 1971 Merc 500, only fitted the 1970 Merc 400 and the 1971 Merc 400 and Merc 500. I never found it on Ebay but did find one new from these folks. Good luck!

OMC started using stainless steel driveshafts in the 50's so corrosion should not be a problem, however any used driveshaft should be checked for excessive wear at the sealing areas. Check the Antique Outboard site at they have a classified section that you can post a want ad.
