Thanks for the information. That's what I suspected but wasn't sure.

those engines do not have a pencil zinc even on the engine, and none in the saildrive.
The older models and Volvo's have them, Yanmar does not its all plastic now.
The one you talk about is all there is.

location of pencil zinc on Yanmar saildrive SD50
My sailboat has a Yanmar 3Jh4E with an SD50 saildrive. I have yet been able to locate the pencil zinc that is purported to be on the upper unit. It is shown in the owner's manual but I can't find it on the saildrive. There is a large zinc just in front of the propeller which I replace as needed.
