Best you change your genset RW impeller. Since it ran dry even for a few seconds no telling the damage the impeller could have suffered. Be sure the RW pump isn't dripping water, seals can fry too when run dry.

Wow.
Never even thought of that.

I definatly started the gen multiple times ( around 8 times) where it would run from 3-10 seconds.
I'm pissed at myself for not taking a better look.
This will be the 4th impeller change on the generator this year.
Except, looks like I'll be doing this one. And good call on the water pump.
The last mechanic said there was a very small drip from it and it should be changed out in the future.

Some pumps can be rebuilt to resolve a dripping seal at a fraction of the cost of a new pump. I bought the seal kit for mine and had a local pump repair shop replace the seals that needed to be pressed into place. It cost about $150 vs. $550 for a new pump.

Don't chuck it in the trash too soon.
