Welcome to our store! 1. Fitment: Manufactured according to original standard specifications, perfect compensation for Marine 89-818997A1 89-818997A2 89-818997t1 89-818998a1 89-818998a2 89-7a185,89-7a185. 2. OEM: The OEM for our electromagnetic relays are 89-850187A1, 89-850187T1, 89-818998A1 for reference. Please double check the part number of your item before purchasing. 3. Practical Function: The starter relay provides high cranking power and reduces the starting current switch. It acts like a transistor, but uses electromagnetic solenoids instead of semiconductors to perform switching. 4. More Durability: The magnetic starter relay is made of solid ABS and metal, so the outer shell is both sturdy and rust-proof, which can provide long-lasting use. 5. Convenient Installation: Manufactured to precisely meet all specifications, the size of the relay's base or interface is precisely matched and can be installed directly without adjustment.
