Sierra 18-3395 3395 Yamaha Water Pump Repair Kit Product Description
Keep your Yamaha outboard running cool and reliable with a fresh water pump rebuild. This repair kit delivers everything needed to restore optimal cooling performance, tackling common issues like impeller wear that lead to overheating during long days on the water. Designed for seamless integration, it helps prevent costly engine damage by ensuring consistent water flow to critical components.
Why Rebuild Your Water Pump Now?
A failing water pump impeller often shows subtle signs before major problems arise: reduced stream from the tell-tale hole, unusual engine temperatures, or debris-clogged housing. Regular maintenance with a quality rebuild kit extends engine life and maintains peak performance. Unlike simple replacements, this kit allows a full teardown and inspection, letting you spot and address corrosion or housing cracks early.
Essential Components for a Thorough Rebuild
- High-Quality Impeller: Precision-molded rubber for maximum grip and longevity, resisting heat and expansion.
- Key and Backplate: Durable materials to align and secure the impeller perfectly.
- Gaskets and O-Rings: Fresh seals prevent leaks and ensure a watertight fit.
- Hardware Kit: Stainless steel fasteners for corrosion resistance in saltwater environments.
Every piece is engineered to match original specifications, making it a go-to for boaters who demand reliability without compromise.
Step-by-Step Installation Tips
- Drain the water from the lower unit and remove the pump housing carefully.
- Inspect the inner workings for wear—replace any damaged cam or liner.
- Lubricate the new impeller with marine grease before installation to ease startup.
- Torque bolts to spec and test flush before hitting the water.
- Prime the system by running in a barrel to confirm strong flow.
Most DIYers complete this in under an hour with basic tools, saving time and hassle compared to full pump swaps.
Boost Longevity with Smart Maintenance
Pair your rebuild with these habits: Flush after every saltwater trip, inspect annually, and store dry. Harsh conditions accelerate wear, but proactive care keeps cooling systems humming season after season. This approach minimizes downtime and protects your investment in the marine lifestyle.
Frequently Asked Questions
What are the first signs my Yamaha outboard water pump needs repair?
Look for weak or intermittent tell-tale stream, rising engine temps, or steam from the exhaust. Early detection prevents overheating damage.
How often should I replace the water pump impeller?
Annually for heavy saltwater use, or every two to three years for freshwater. Always check during off-season storage.
Can I install this kit myself without special tools?
Yes, basic wrenches, screwdrivers, and pliers suffice. A service manual helps with torque specs for best results.
Does this kit fit all Yamaha models?
It's tailored for specific Yamaha outboard ranges—verify compatibility with your engine's year and horsepower for a perfect match.
What lubricant works best during installation?
Use a water-resistant, high-viscosity marine grease on the impeller splines and keyway to reduce friction on first startup.
How do I test the pump after rebuild?
Run the engine in a test tank or with muffs, checking for a steady tell-tale flow before trailering to the water.
Will this fix overheating in saltwater?
Yes, by restoring impeller efficiency and sealing out corrosion, but combine with regular flushing for best protection.
Equip yourself with this rebuild kit and stay ahead of cooling failures—reliable performance awaits on your next adventure.
