Cooling system

[bax]

Can anyone tell me if Tohatsus and Nissans have an anti-corrosion protective coating on the inside surfaces of the cooling system? Specifically the 9.8 4 strokes?

Yes. Zinc coating on the water passages. See http://www.tohatsu.com/tech_info/brochure_pdfs/2010_brochure/Toh2010_8-20.pdf
