This small pin prevents the impeller from spinning independently of the shaft, ensuring all pump shaft rotation is transferred directly to impeller rotation for maximum coolant flow. A sheared or missing dowel pin causes the impeller to freewheel on the shaft — the pump shaft turns but the impeller does not, resulting in immediate loss of coolant circulation and rapid overheating.\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.
