A nylon washer serves as a sealing and load-distribution element used at fastener and fitting locations throughout an outboard motor. The nylon material allows the washer to compress slightly under torque, creating a secure, leak-resistant interface that protects mating surfaces from damage. When a washer of this type is worn, cracked, or missing, the joint it sits in can weep fluid, allow fastener movement, or permit surface damage that leads to more extensive repairs.
