Example question · Yanmar inboard diesel
BoatGuru’s answer
A Yanmar inboard’s raw-water/seawater pump is typically a compact engine-driven pump with a small removable front cover. Behind that cover is a flexible rubber impeller: a hub with multiple bendable vanes. As it rotates, the vanes flex against the pump housing, drawing outside water in and pushing it through the cooling circuit—commonly through a heat exchanger and then out with the exhaust. It does not circulate the engine’s internal coolant on models that use a heat exchanger.
Yanmar’s general maintenance reference:
What is your Yanmar engine model and, if known, the cooling-system arrangement?
