Pro Marine Cylinder Head Gasket for Suzuki DF70A DF75AT DF80A DF90A and DF100BT 4-Stroke Outboards

The Pro Marine 8714 Cylinder Head Gasket is an aftermarket replacement for select Suzuki 70 HP, 75 HP, 80 HP, 90 HP, and 100 HP 4-stroke outboard engines. It replaces Suzuki OEM part number 11141-87L00.

Compatible applications include select Suzuki DF70A, DF75AT, DF80A, DF90A, and DF100BT engine configurations. The supplied application data includes DF70A, DF80A, and DF90A catalog listings beginning in 2009, along with later model variations listed through 2026.

The cylinder head gasket seals the mating surfaces between the engine block and cylinder head. It helps maintain combustion chamber compression while separating the engine's cooling water and lubrication passages.

Important: Confirm your Suzuki engine model, serial number, and original OEM gasket number before ordering. Not every Suzuki 70-100 HP outboard uses the same cylinder head gasket.
