How to Match This Part

This is a flexible rubber raw water pump impeller. It sits inside the pump housing behind the cover plate and is driven by a splined shaft. It replaces the primary original part number Johnson 09-842B for the Johnson F98 pump.

Match this part by checking your engine in this order:
1. Original impeller part number (stamped on the old impeller or listed in the pump section of your parts catalog)
2. Blade count (this listing is 12 blades)
3. Drive type (this listing is a spline hub, about 25.4 mm / 1 in bore)
4. Diameter and width (this listing is 95 mm diameter and 180 mm wide, not F95 09-820B which is 130 mm wide)

Identify it physically before ordering. Johnson 09-842B is a tall 12-blade neoprene impeller, 95 mm diameter and 180 mm wide, with a brass spline insert. Catalog photos of the service pack show an O-ring and lubricant; this listing is the impeller only. SPX Johnson charts do not list a Jabsco equivalent for the F98 impeller.

  • ✓ Primary OEM: Johnson 09-842B
  • ✓ Product form: 12-blade neoprene impeller, brass spline insert, 95 × 180 mm
  • ✓ Fitment: part number, then 180 mm vs 130 mm F95 09-820B

Part Number Cross-Reference

Use this table to confirm equivalent part numbers. Genuine Johnson service kits include an O-ring and glycerine. This listing is the impeller only.

Compatible Engine Models

Confirm the original impeller number and measure 180 mm width on a 95 mm 12-blade spline impeller. Do not assume every Johnson F9 / F95 pump uses this impeller.

Package Contents

This listing is for the impeller only. Product photos of a genuine-style pack show an O-ring and lubricant sachets; those extras are not included. Please refer to the part number cross-reference table to confirm component details.

Cover gasket, O-ring and lubricant are not included.

Installation Guide

  1. 1 Stop the engine, let it cool, and close the raw water seacock so water cannot enter the boat while the pump is open.
  2. 2 Remove the cover plate screws and lift off the cover. Keep the screws and the old gasket together so you can compare the seal size when reassembling.
  3. 3 Note the spline orientation, then grip the brass insert and pull the old impeller straight off. This impeller is 180 mm wide; recover any broken vane pieces from the downstream cooling circuit before continuing.
  4. 4 Clean the housing bore and the wear plate, and inspect them for scoring. Apply a marine-grade impeller lubricant, glycerine or soapy water to the bore and the new vanes. Do not use petroleum-based grease, which attacks neoprene.
  5. 5 Align the spline insert with the pump shaft, then press the impeller in while turning the shaft in the normal direction of rotation so all twelve vanes lay over the same way.
  6. 6 Refit the cover plate with a serviceable gasket or O-ring, tighten the screws evenly in a crisscross pattern, open the seacock, then start the engine and confirm a solid stream of cooling water and no leaks at the cover.

Note: Professional installation is recommended to ensure safety and optimal performance.

Troubleshooting & FAQ

How do I confirm this fits my engine? +

Start from the original impeller number. If the old part is Johnson 09-842B for an F98 pump, and it is a 12-blade 95 mm impeller 180 mm wide on a spline hub, this listing is the correct size.

Is this the same as 09-820B? +

No. Johnson 09-820B is the F95 impeller, 95 mm diameter and 130 mm wide. This listing is the F98 impeller, 180 mm wide. Measure the old part.

The photo shows an O-ring and lubricant. Is this a kit? +

This listing is the impeller only. The supplied photo is a genuine-style service pack. Excel kit contents are empty, so the O-ring and lubricant are not included.

Is there a Jabsco number for this impeller? +

SPX Johnson charts list 09-842B for F98 with no Jabsco equivalent. Excel still prints 09-842B on a Jabsco row. Match Johnson 09-842B.

Is this an OEM or aftermarket part? +

This listing is an aftermarket replacement part and is not an OEM component. We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

How fast do you ship and how much does it cost? +

We offer fast global shipping, typically 5–15 days worldwide, and standard shipping is free. Expedited options are available at checkout depending on your location.

What is your warranty and return policy? +

This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window for unused items in original condition; please see our policy page or reach out for instructions.

Important Notes

  • Verify that the product images and specifications match your original part. If discrepancies exist, even if your model is listed, do not proceed with the purchase.
  • This product is an aftermarket replacement part and is not an OEM component.
  • This listing is the 180 mm F98 impeller. It will not fit F95 09-820B, which is 130 mm wide on the same 95 mm diameter.
  • The impeller is supplied on its own. Cover seals and lubricant must be ordered separately if your service procedure requires them.
  • Never run the pump dry. Even a few seconds without water will damage the neoprene vanes.
  • Professional installation is recommended to ensure safety and optimal performance.
