Thinking of adding drive shower are they all stainless?

[XLI]

Hello,

I just purchased a CS22 with a B3 drive and would like to start from day 1 giving every advantage to maintaining the drive system. I have read about the B3 struggles with corrosion due to the big stainless props. I know folks say to add the prop nut zinc, but it seems like there are still some that have issus - even in fresh water and on trailer boats. This may not still be an issue with new drives but I haven't read where they changed anything on newer drives. With the Simrek being stainless would anyone have concern about making the problem worse? My boat won't spend a lot of time moored. Maybe 3 weeks or so a year in fresh water. Is it better to battle the heat or corrosion. Which one is the more likely the bigger issue?

Thanks!

Those issues were from prev years. I haven't heard of the issues on later drives. That would be the first thing I would put on any merc drive.

I'm just knowledge seeking here, but is this correct that a brand new Bravo III drive requires the owner to install an aftermarket cooling system to avoid overheating the outdrive? I know VP isn't perfect, but how can a manufacturer as old and large as mercury not have this detail covered in the design?

Not required by Merc., but a strong consideration to stop the chalky residue deposits on the upper gearcase.

B3's have always suffered from high running temps. The chalky-ness is from boiling the water instantly at the surface of the drive once they're dunked back into the water after a prolonged run.


FWIW... I just bought a new-to-me boat and drive showers will be the first addition to the B3X drives.

I definately will be adding one of these though I would suspect drive lube has improved since the B3 was first rolled out.

Honestly that lube prob hasn't changed in a very long time.
