Johnson Pump 09-1027BT Neoprene Impeller Kit for F5B-905 Pump, Volvo Penta 3857794 Replacement

The Johnson Pump 09-1027BT is a neoprene impeller kit built to service the Johnson Pump F5B-905 raw water cooling pump, the OEM replacement pump for Volvo Penta 3857794. The impeller inside this kit is molded from neoprene, a rubber compound chosen for raw water pump service because it holds its shape and seal quality through repeated wet/dry cycles and resists the wear that comes from constant rotation against the pump cam and housing. As the wear component of the F5B-905 pump, this impeller is the part that typically needs periodic replacement to keep raw water flow and engine cooling performance consistent, since a worn or cracked impeller is one of the most common causes of reduced water flow and overheating in raw water cooled marine engines.

This kit is intended for boat owners and marine technicians servicing the F5B-905 pump on Volvo Penta gasoline sterndrive and inboard engines. It is also cross-referenced as an equivalent to a green Jabsco neoprene impeller of the same specification, giving buyers an alternate source for a matching replacement impeller when servicing this pump.

Frequently Asked Questions

What pump does the Johnson Pump 09-1027BT impeller kit fit? The 09-1027BT is a neoprene impeller kit built for the Johnson Pump F5B-905 raw water cooling pump, which is the OEM replacement pump for Volvo Penta 3857794.

Is this impeller made of neoprene or nitrile? The impeller in the Johnson Pump 09-1027BT kit is made of neoprene, a rubber compound valued in raw water pump impellers for its shape retention and seal quality under repeated wet and dry running.

Does the 09-1027BT interchange with a Jabsco impeller? Yes, Johnson Pump 09-1027BT is interchangeable with the Jabsco 0303-007-P(Green) neoprene impeller, so either part number can be used to service the same pump.

Which Volvo Penta engines use the F5B-905 pump that this impeller fits? The F5B-905 pump serviced by the 09-1027BT impeller kit is used on a wide range of Volvo Penta gasoline engines, including 3.0, 4.3, 5.0, 5.7, 5.8, 7.4, and 8.2 liter models such as the 4.3GSPNCA, 5.7GLPLKD, and 7.4GIPBYCCE series.

Is 09-1027BT a genuine Johnson Pump part? Yes, the 09-1027BT neoprene impeller kit is a Johnson Pump part, and Johnson Pump is the original manufacturer of the F5B-905 cooling pump it services.

How do I know if my impeller needs replacing? Reduced raw water flow or engine overheating on a Volvo Penta engine equipped with the F5B-905 pump is often caused by a worn or cracked impeller, which the 09-1027BT neoprene impeller kit is designed to replace.

Can I use the Jabsco 0303-007-P instead of the Johnson Pump 09-1027BT? Yes, because the Jabsco 0303-007-P(Green) is listed as interchangeable with the Johnson Pump 09-1027BT, both impellers serve the same replacement function in the F5B-905 pump.

What OEM pump does the 09-1027BT cross-reference to? The 09-1027BT impeller kit is used in the pump that replaces Volvo Penta OEM part 3857794.

Is the 09-1027BT sold as just the impeller or a full kit? The 09-1027BT is sold as the F5 Neoprene Impeller Kit, built specifically to service the impeller in the Johnson Pump F5B-905 raw water pump.

Will this impeller run dry without damage? Specific dry-run tolerance is not specified for the neoprene impeller in the 09-1027BT kit; it is designed as a direct wear-item replacement for the F5B-905 pump's original impeller.
