Mercruiser BIII Winterization

[MExcelsior]

Quick question: My brother had his impeller and u-joints, etc. lower unit maintenance last year and since this is done every two years, wants to winterize himself. (With my help). Question, I am very familiar with the winterization of a 4.3 mpi, but wanted to know if I need to do anything different with the BIII?

Please let me know!

Thanks,
Mike

Change the drive oil and grease the fittings. Not much to do with the out drive itself when it comes to winterizing
