Impeller Kit 920-0001 09-1028B 18200 18-3077 877061 for Volvo Penta Yanmar Jabsco Johnson Sherwood Raw Water Pump 8 Blade 65 mm 50 mm Spline Drive — Germany Local Warehouse
Product Overview
Impeller kit for the large raw water pumps on Volvo Penta, Yanmar, Jabsco, Johnson and Sherwood installations, a service part measuring 65 mm (2.56 in) across and 50 mm (1.97 in) wide with eight blades on a 15.8 mm (0.62 in) spline shaft. It replaces Jabsco 920-0001, Johnson 09-1028B, Sierra 18-3077 and the cross numbers below. Shipped from our Germany local warehouse.
The pack holds the impeller, the pump cover gasket and the O-ring. On these pumps the cover comes off every service, so the seals are disturbed whether or not they look tired, and a two euro gasket that fails costs an engine.
Fitting is straightforward once the hub is square on the shaft. Forced on at an angle, the impeller runs off centre, one side of the blades wears away and the brass hub strips. Seat it by hand, check it turns with the shaft, then fit the cover.

Service Interval and Engine Hours
| Engine Hours per Year | When To Change | Why |
|---|---|---|
| Under 50, club boat on a lake | Every second season, before launch | Hours are low but the blades still cure |
| 50 to 100, coastal cruising | Every season | One season is the safe interval on salt water |
| 100 to 200, long distance motorboat | Every season, check at half way | Blades wear faster on long runs at cruise |
| Over 200, charter or working boat | Twice a season | Change on hours, not on symptoms |
| Liveaboard, diesel run daily | Every 250 hours | Gensets and main engines both count |
| Any overheat event | Immediately | Heat damages the blades even if they look fine |
Winter Lay Up in Germany
| Lay Up Practice | Effect on the Pump | What To Do |
|---|---|---|
| Engine raw water drained in October | Pump body empty and dry | Fit the new impeller in spring, not before |
| Water left in the pump below 0 °C | Ice splits the cover and the housing | Drain the pump before the first frost |
| Impeller left in the housing all winter | Blades take a set and harden | Remove it or renew it in spring |
| Boat under cover, engine bay damp | Cover screws corrode into the housing | Grease the screw threads at lay up |
| First launch in April | Dry start on a set blade | Prime the pump before the engine starts |
| Baltic and North Sea salt water | Salt crystals on the blades and the cam | Fresh water flush before storage |

| 5 | Grease the bore lightly and fold the blades in the running direction |
| 6 | Slide the impeller on square and turn the shaft to confirm it drives |
| 7 | Fit the new gasket and O-ring dry, tighten the cover evenly |
