What This Part Is

Jabsco 17935-0001-P is a genuine Profile Q neoprene flexible impeller kit for large-capacity marine engine cooling and water-transfer pumps. It features a 12-blade neoprene impeller measuring 3-3/4 in. diameter × 2-1/2 in. wide with a 1 in. spline hub. Jabsco specifies this neoprene compound for engine-cooling and fresh- or salt-water transfer applications. The kit includes the impeller, replacement gasket, spline seal, and installation lubricant.

Note: The 17935 (2-1/2 in. wide) and 17936 (3-1/2 in. wide) share the same diameter and hub but differ in width — confirm the width of your original impeller before ordering.

Compatible Pump Applications

Primary Jabsco pump families:

• Jabsco 6400-series
• Jabsco 7420-series
• Jabsco 3570, 6590, 10880, 10980, 21680, 29770, 52200, 52220 series (confirm by impeller spec)

Cross-Reference Applications

Documented OEM cross-references include raw-water pumps used on selected:

• Caterpillar marine engines — refs 5L6042, 5N9360, 1W9046
• Detroit Diesel marine engines — refs 5196628, 8924838
• Volvo Penta TAMD-series diesel engines — refs 875660, 875736-1, 825942, 807904
  Documented TAMD applications: TAMD71B, TAMD73P-A, TAMD73WJ-A, TAMD74A, TAMD74C-A, TAMD74L-A, TAMD74P-A, TAMD75P-A

• Onan — ref 500135
• Johnson Pump — ref 09-819B / 09-819B00
• Oberdorfer — ref J050035

Compatibility is determined by the installed pump model and original impeller reference, not engine manufacturer alone. Confirm by pump number and physical dimensions before ordering.

Fitment Notice — Dimensional Confirmation

Large marine impellers can look very similar while differing in width, shaft size, or compound. The correct 17935-0001-P should measure:

• OD: 3-3/4 in. / 95 mm
• Width: 2-1/2 in. / 63.5 mm
• Hub: 1 in. / 25.4 mm spline
• Blades: 12
• Compound: Neoprene

Do not confuse with Jabsco 17936-0001-P, which shares the same diameter and hub but is 3-1/2 in. / 89 mm wide (wider). If the dimensions do not match, do not assume interchangeability based on engine make alone.

When to Replace

Replace the impeller during scheduled cooling-system maintenance, or if inspection reveals:

• Cracked or split vanes
• Missing blade sections
• Permanent blade deformation (blades no longer spring back)
• Hardened or brittle neoprene
• Reduced seawater flow or poor pump priming
• Heat damage from running dry
• Excessive blade-tip wear
• Debris damage inside the pump

Jabsco recommends preventive impeller replacement rather than waiting for complete failure.

Service Interval

Inspect annually during cooling-system service. Replace at least annually, or earlier based on duty cycle and operating conditions. If the engine or pump has run dry at any point, inspect and replace the impeller immediately.

Installation Notes

• Shut off the raw-water supply and close the intake seacock before opening the pump
• Remove the pump end cover and all old sealing components
• If the old impeller is missing any blades, locate and remove all fragments from downstream hoses, coolers, and heat exchangers before reassembly
• Inspect the pump bore, cam, wear plate, shaft, splines, and cover plate for scoring or wear
• Lubricate the new impeller before installation — this protects the blades during initial dry-start priming
• Align the spline hub fully with the pump shaft and make sure all 12 blades seat evenly inside the housing
• Install the replacement gasket and spline seal included in the kit — do not reuse the old gasket
• Reopen the seacock and verify strong, steady water flow immediately after startup

Parts Desk Insights

Best use case: 17935-0001-P is most commonly ordered for scheduled annual impeller replacement on large Jabsco-pumped commercial and high-duty-cycle diesel inboard engines — particularly Caterpillar, Detroit Diesel, and Volvo Penta TAMD installations. The kit format is the right choice because the gasket and spline seal should be replaced at every impeller service.

Common issue: The most frequent ordering mistake is confusing 17935-0001-P with the wider 17936-0001-P. Both impellers are 3-3/4 in. in diameter with a 1 in. spline hub and 12 neoprene blades — the only external difference is the width (2-1/2 in. vs. 3-1/2 in.). Measure the original impeller width before ordering. If the original part number is illegible, the dimensional check is the most reliable way to confirm the right part.
