Yanmar 119574-42530 Impeller Kit for 6LY2
The Yanmar 119574-42530 is the factory impeller kit for 6LY2 Series engines. It is the service item for the raw water pump, packaged the way the job is actually done rather than as a single part.
The reason a kit beats an impeller on its own is the cover joint. Once the end cover comes off, its seal has been disturbed, and a cover that does not seal draws air instead of water - which shows as a pump that loses prime, a weak exhaust stream and an engine that runs warm for no visible reason. Having the right seal in the box removes the most common cause of a rebuild that has to be done twice.

Frequently Asked Questions
Q: The old impeller is missing a vane. Does the kit cover that?
The kit gets the pump running again, but the missing piece still has to be found. Check the heat exchanger inlet before you call the job done.
Q: Can I use it as a preventive spare rather than fitting it now?
That is exactly what it is best kept for. Store it out of sunlight and away from heat and it will be ready when it is needed.
Q: What is the advantage over buying the impeller alone?
The cover seal is disturbed as soon as the pump is opened, and a cover that does not seal properly draws air rather than water. The kit puts that right in the same part number.
Q: How often should this service be done?
Once a season for a boat in regular use, or to the engine service schedule. Rubber ages on the shelf and in the pump, so time matters as much as running hours.
