I've decided to pull the pump off myself. I already ordered all the

gasket.. Impeller.. $50 worth of stuff..

Is there anybody who did this before? Do you have tips?

You may want to have the faceplate re-surfaced if it has been scored or
scratched. Otherwise, just use a good waterproof grease and assemble
carefully. The shop manual will help. I suspect that the same pump was
used on quite a few of the old MD series engines so perhaps you can pick up
the manual easily.

In times gone by I learned that grounding out, and subsequently pumping sand
or dirt through while trying to get off, eventually made re-building the raw
water pump a requirement. That's how the face plate got scored.

Note that I sometimes find myself in places where the charts just don't cut
it. Also note that I sometimes also find myself just not paying enough
attention.
