Right Time to Replace Anodes

After pulling up the schematic of the df70 on I boats found an anode on the exhaust side and on the intake side of the motor.I ordered replacement anodes, my motor has just under 900 hrs and has been rinsed with saltaway after every use.I was disapointed that this was not covered in the Susuki manual that I have.

Fishingmark I wondered about that cover on the exhaust manifold but neglected to pull up the Browns point diagram. Thanks to a fellow c-brat I'm on track again!! Thumbs Up

Why would you need anodes in the inlet?

Thanks all for this discussion. I have twin F80 Yamahas (2003), approx 800 hrs on them, not stored in water, religiously flushed after every trip. I looked in the Service Manual, it doesn't specifically mention to check or maintain them, but does show where all 5 anodes are located: 3 internal, skeg/trim tab, and bottom of motor mount.

I wire-brushed the 2 external ones to like new. I wish I knew whether they are zinc or mag or some other metal, I'll have to find out. I found and removed the internal ones all under the cowling, 2 under a rear, plastic cover and 1 on the lower right side of the engine (as viewed facing from rear of motor). All three are identical, easily removed with 2 bolts each. Mine had nearly all of the original material left, so I scrapped them with a knife and brushed to a bright, shiny surface. O-rings for sealing were in good shape.

See pictures in my album under maintenance.
