Sierra 18-3240 Water Pump Kit-Chrysler/Force Product Description
Keeping your outboard motor cool under pressure is non-negotiable, especially when you're out on the water chasing the next big catch or cruising with family. A worn-out water pump can lead to overheating, engine damage, and cut adventures short. That's where a reliable replacement like this kit steps in, designed specifically for Chrysler and Force outboards. It restores proper water flow to prevent those dreaded high-temperature warnings and keeps your engine running smoothly season after season.
Engineered for Durability and Performance
- High-Quality Impeller: Nitrile rubber construction resists wear from sand, debris, and constant exposure to saltwater, ensuring long-lasting pumping action.
- Complete Rebuild Kit: Includes impeller, wear plate, housing gaskets, and O-rings—everything needed for a full refresh without hunting for mismatched parts.
- Precision Fit: Matches original equipment specifications to eliminate leaks and maintain optimal cooling efficiency.
- Corrosion-Resistant Materials: Stainless steel and bronze components battle harsh marine environments, from freshwater lakes to salty bays.
Boat owners rave about how this setup breathes new life into older motors, often extending their usability for years with proper care.
Perfect Match for Chrysler and Force Outboards
This kit fits a wide range of models from the Chrysler and Force lineup, covering everything from 4 to 40 horsepower engines produced during their prime manufacturing years. Whether you've got a classic Force 9.9 or a Chrysler 18, it slides into place like it was built yesterday. Always double-check your engine's serial number against known compatible ranges to confirm, as variations exist across production runs.
Why Upgrade Your Water Pump Now
A failing water pump doesn't announce itself with fanfare—it sneaks up with subtle signs like steam from the tell-tale, sluggish cooling, or rubber bits in the pee stream. Ignoring it risks warping heads or seizing pistons, turning a simple fix into a rebuild nightmare. Installing this kit proactively:
- Boosts cooling capacity for hotter days and heavier loads.
- Reduces downtime, so you're rigging up instead of troubleshooting.
- Saves money over dealer-priced OEM parts while matching quality.
- Improves fuel efficiency by ensuring consistent engine temps.
Pro tip: Flush your cooling system thoroughly before install to remove old debris and maximize the kit's lifespan.
DIY-Friendly Installation
No shop required for most handy boaters. Drain the lower unit, remove the old pump assembly (usually 4-6 bolts), clean the mating surfaces, and press in the new impeller with a proper tool to avoid damage. Lubricate O-rings with marine grease, reassemble, and test-run in a barrel. Takes under an hour with basic tools like a socket set and impeller installer. If you're new to it, watch for alignment marks on the impeller keyway to sync with your driveshaft.

Long-Term Care for Peak Performance
To get the most from your investment:
- Inspect annually or every 100 hours—look for impeller cracks or glazing.
- Use ethanol-free fuel and add stabilizer to prevent rubber degradation.
- Winterize by running antifreeze through the system.
- Monitor tell-tale flow; weak stream means check it again.
With routine checks, this kit can outlast multiple seasons of hard use.
