Compatibility and Fitment
This impeller fits Jabsco flexible impeller pumps that use the M-profile, key-drive hub on 16mm shafts and require a 65mm diameter by 51mm depth rotor. Measure the old impeller and confirm shaft type and hub before ordering. If your existing pump manual specifies 4598-0001 or 4598-0001-P, this is the correct neoprene replacement.
Compliance and Safety
Replace flexible impellers proactively as part of routine engine servicing. Always isolate power, close seacocks, and follow the pump manufacturer’s service instructions. After installation, check for leaks, prime the pump, and verify cooling flow at idle and cruising rpm.
Marine Applications
Ideal for raw-water cooling on petrol and diesel engines, generator sets, and auxiliary seawater transfer where neoprene is suitable. Neoprene handles seawater and small traces of oil well and offers good flexibility for cold starts.
