Questions & Answers
Is this a genuine original part?
This is a genuine SEAFLO 42-Series pump, manufactured to the highest marine standards for high-performance and durability.
How do I know if it is compatible?
Compare your existing pump's voltage (must be 24V) and flow rate. This model uses standard 1/2" MNPT threaded fittings, making it a direct replacement for most Shurflo and Jabsco pumps with similar specifications.
Do I need an accumulator tank with this pump?
No, the internal bypass technology handles low-flow demand without the rapid cycling typical of older pumps, eliminating the strict necessity for an external accumulator tank.
Note: Please verify your system voltage is 24V before purchasing. For the 12V version, please see our other listings at 4boats.co.uk.
