You can cross-reference the OEM part number 25700-87L00 or 25700-87L01 using Suzuki's parts diagrams linked above to confirm compatibility.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace the lower unit seals?\u003c\/strong\u003e\u003cbr\u003e\nA: Replace seals whenever you perform major lower unit service, such as gear replacement or bearing work. Inspect seals annually and replace immediately if you notice gear oil leaks, milky oil (indicating water intrusion), or after any lower unit impact or damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are signs that my lower unit seals are failing?\u003c\/strong\u003e\u003cbr\u003e\nA: Common indicators include visible gear oil leaking from the gearcase, water-contaminated oil (milky appearance), excessive gear noise, difficulty shifting, or a drop in gear oil level between regular checks.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse old seals if they look okay during disassembly?\u003c\/strong\u003e\u003cbr\u003e\nA: No, always install new seals during lower unit service. Even seals that appear intact lose their sealing ability once removed, and reusing them may lead to premature failure and water intrusion into the gearcase.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need special tools to install this seal kit?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, proper installation requires seal drivers or installation tools sized to match each seal, a torque wrench, gear oil pump, and basic hand tools. A service manual for your specific engine model is highly recommended for torque specifications and assembly procedures.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between OEM and aftermarket seal kits?\u003c\/strong\u003e\u003cbr\u003e\nA: This listing is an aftermarket replacement part (not an OEM component).
