Hi,
I have some corrosion on the lower unit of my 2006 Yamaha F150 and while researching my options for the removal of this corrosion I ran across some posts about zinc's so I have started to wonder if I have the proper zinc's on my motor and could that contributed to my corrosion. It is my understanding that "freshwater = magnesium, brackish = aluminum, salt = zinc" but I use my boat in both fresh and saltwater. Don't know if it matters but I have a stainless prop.
The zinc on the outboard shows very little corrosion and has never been replaced.
Two questions:
How do I tell what type of zinc my motor has now?
Considering the fresh and saltwater use, what zinc should I use?
Thanks in advance for your advice.
Charlie
