PURPOSE: An engine exhaust manifold heat exchanger for a watercraft is provided to support and control the position of an annex pipe of watercraft engine neighboring. CONSTITUTION: An engine exhaust manifold heat exchanger for a watercraft comprises a housing block(101), a cooling water inflow opening(110), a cooling water outlet(120), and an inner baffle. The housing block is the shape wrapping an exhaust manifold(210). The housing block is formed to an engine block(200). The cooling water inflow opening is equipped on one end of the housing block. The cooling water inflow opening makes the cooling water supply to the housing block inside. The cooling water outlet is equipped on the other end part of the housing block. The cooling water outlet is formed the cooling water flowed in from the cooling water inflow opening is ejected as the housing block outside. The inner baffle divides a coolant flow isolated from the inside space of the cooling water inflow opening and the housing block. |
