Anyone out there know how many zincs there are on a 315hp Peninsular, and more importantly, where the heck they're located??
I found and replaced the one in the heat exchanger. Not seeing any other obvious ones I took a look at the manual for the engine that came with my boat. The ONLY zinc it lists is the one I've already found.
This just seems wrong. I'd assume that the aftercooler would have one as well as the trans. oil cooler.
So...are there others?

Thanks,
Doug
