Jabsco 50880 Shower Drain Pump Service Kit, For 50880-1000/1100

Overview

The Jabsco SK880 is a service kit for Jabsco 50880 shower drain and bilge pumps. It fits 50880-1000 and 50880-1100 pumps, so it covers both the 12V and 24V versions used for shower drain, auxiliary bilge, and general drainage duty on board.

The matching 50880 pump platform uses 19 mm (3/4 in) or 25 mm (1 in) port connections and is self-priming to 3 m (10 ft), which makes correct service-kit fitment more useful than broad category matching. This kit focuses on the pump head service parts that typically get replaced during maintenance, so you can refresh the wet end without changing the full pump assembly.

Key features

• Fits Jabsco 50880-1000 and 50880-1100 diaphragm pumps
• Covers both 12V and 24V versions in the 50880 range
• Replaces core wet-end parts including the diaphragm, joker valves, and ports
• Lets you service the pump head instead of replacing the complete pump and motor assembly
• Matched to the 50880 pump layout that uses 19 mm (3/4 in) or 25 mm (1 in) port connections

Compatibility and fit

This kit is for the Jabsco 50880 series only. Before ordering, check the pump label and confirm the model is 50880-1000 or 50880-1100. It should not be treated as a universal rebuild kit for other Jabsco diaphragm pumps that may look similar once installed in a bilge compartment, shower sump space, or locker.

For boats that rely on a 50880 pump to clear shower drain water or handle light bilge and utility drainage, the SK880 gives you the parts normally changed when flow falls off, priming gets inconsistent, or valve sealing is no longer clean. That makes it a good fit for routine maintenance on cruising boats, fishing boats, and service craft already set up around this pump family.

Installation and service

When the pump goes back together, keep the suction side airtight and check hose condition at the same time. The 50880 pump uses multi-position ports, which helps when space is tight, and if the unit is mounted vertically the motor should sit above the pump head. On boats kept in saltwater, it also makes sense to inspect the surrounding wiring and motor area while the pump is apart, since corrosion around drainage equipment tends to show up long before a full failure.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
