Overview
A patented X-Air Impeller does the work in the Tsunami Mk2 T500, which is built to eliminate air-locks and hold a consistent flow. The housing is plastic, and two outlet styles come in the box with a backflow valve and a washer.
A compact pump that drops into the spot of the older model and brings its own fittings. The title calls it manual and no automatic sensor is described, and the flow rate in the specs reads as a gallons-per-minute typo.
Who it's for
Small-boat owners who want a compact manual bilge pump with fittings included. Anyone who needs automatic operation, a higher flow rate or wiring guidance should look at a different model.
Pros and cons
- Patented X-Air Impeller
- Fittings and valve included
- Direct swap for older model
- Five year spare part availability
- Manual operation, no auto sensor
- Flow rate typo in specs
- Wiring details missing
Performance notes
The impeller moves water out of the bilge, and its design aims to avoid the stalled priming that air pockets cause. Lift height limits how high the hose can run, and the non-return valve stops water draining back after the pump stops.
