Yanmar Impeller Help!

[Charlie]

I'm off to the airport then to Cinque Terra by car Wed Morning. Perhaps we will catch up when there. Really like that yard. Good people.

Here's where we were stuck for two days off Elba, Italy. Ended up snorkeling, hookah diving, paddle boarding, swimming and napping. That's us in the middle of the picture with the white hull.

Much nicer having impeller issues here than most other places.

Thank you everyone for your helpful ideas.

Inspired by this thread I changed my impeller yesterday.

Wot names part numbers are correct.

I had at least one of each type and was able o compare.

Ken, some people recommend that you remove the impeller when you lay up the boat for the winter. Clean it and seal it in a freezer bag.

Here's a picture of the old impeller, glad we changed it. Several fins half missing, with most cracked and ready to let go. From now on, this will be changed annually, NOT after 1000 hours like the service manual recommends.

Off to Cinque Terre in the morning.

Great outcome

I was not envious of your impeller problems, especially given your lack of access but I'm very envious of your plans to visit Cinque Terre.
