Sierra 23-3312 Impeller Kit, Fischer Panda

Keep your Fischer Panda marine generator running smoothly on the water with the Sierra 23-3312 impeller kit. Designed as a direct replacement for the original equipment, this kit tackles one of the most common failure points in diesel generators: the rubber impeller that circulates cooling water. Over time, these impellers wear down from debris, dry running, or age, leading to reduced flow, overheating alarms, and potential engine damage. Installing this kit restores full cooling performance, giving you peace of mind during long passages or heavy-use anchoring.

Precision Engineering for Reliable Performance

Sierra crafts these impeller kits with high-grade neoprene rubber that resists hardening, cracking, and swelling in saltwater environments. Unlike generic parts that might fit loosely or degrade quickly, the 23-3312 features exact vane geometry to match Fischer Panda's pump specifications. This ensures maximum water uptake even at low RPMs, preventing the cavitation that plagues worn impellers. Boaters report pulling this kit from their spares box during surprise failures and getting back online in under an hour—no special tools required.

Complete Kit for Hassle-Free Replacements

Every Sierra 23-3312 kit arrives with the impeller, O-rings, gaskets, and hardware tailored for Fischer Panda generators. No hunting for missing seals at remote marinas. The included lubricant simplifies insertion, reducing the risk of tearing vanes during install. It's a smart upgrade for proactive maintenance, especially if your generator logs high hours in tropical waters where heat accelerates wear.

Key Features at a Glance

• Durable neoprene construction for extended service life
• Full hardware kit minimizes downtime
• Corrosion-resistant materials suited for marine conditions
• Pre-lubed design for easier handling

Step-by-Step Installation Guide

Replacing the impeller is a straightforward DIY job that most owners handle during annual haul-outs. Here's how to do it right:

1. Shut down the generator, close the seacock, and relieve pressure by cracking a hose.
2. Remove the pump end cover—usually just a few screws.
3. Extract the old impeller with needle-nose pliers or a dedicated puller; inspect for debris in the housing.
4. Apply a thin layer of silicone-based lubricant to the new impeller and slide it in, aligning the keyway.
5. Reinstall seals, cover, and torque to spec. Prime the system with fresh water before restart.

Pro tip: Rotate the impeller by hand before closing up to confirm free movement. Test-run at dockside to verify flow.

Extend Your Generator's Life with Smart Maintenance

Impeller failure often stems from neglect, like running dry during strainer clogs or winterizing without fogging. Pair this Sierra kit with a raw water strainer screen and annual inspections to hit 2,000+ hours between changes. In high-silt areas, check every 500 hours. Freshwater flushing after use preserves the rubber, too. Owners who stay on top of this routine avoid costly overhauls and keep insurance surveys happy.

Why Sierra Stands Out in Marine Spares

Sierra's reputation among diesel generator users comes from rigorous testing against OEM standards—think pump flow benchmarks and accelerated aging trials. It's not just a part; it's a reliable spare that mirrors factory performance without the premium markup. Whether you're outfitting a trawler, sailboat, or workboat, this kit delivers the dependability that keeps you generating power when it counts.
