Oil seals do a deceptively difficult job: keeping pressurized oil inside a rotating shaft housing while keeping water completely out, on a part that's submerged or splashed continuously. A failed propeller shaft seal is one of the most common causes of water intrusion into the lower unit gearcase, often only discovered when the gear oil is drained and found milky with water contamination.
Boat Max Online stocks genuine Suzuki OEM oil seals for the crankshaft, propeller shaft, drive shaft, and lower unit housings. Each seal is sized and constructed in the specific material and lip configuration Suzuki specifies for its location, the propeller shaft seal in particular sees constant water exposure and rotational wear that a generic seal isn't engineered to withstand long-term.
As an authorized Suzuki Marine dealer, every seal we sell matches genuine Suzuki dimensions and material specification. Free shipping on orders over $499 to the lower 48 states.
