Yanmar 56 hp

I do not see that this engine has a zinc in the heat exchanger, does anyone know to the contrary I have a 393 Beneteau 2002 model 56 hp Yanmar

I have the same boat, same engine. Does not have a zinc.

My 76hp in a H466 does not have zincs either.

Yanmar isolates the raw water / fresh water circuits from each other eliminating the need for a sacrificial zinc. In fact, they market their marine powerplants as designed and built for marine use, not "marinized".

Make sure you follow Yanmar's fresh water coolant directives carefully.
