Onan 13.5K adequate water flow?

[Dayton40]

I may be dreaming but after replacing my impeller on my Genset (and removing several bits) it seems I don’t have the same flow. It’s a consistent minimal flow but it doesn’t seem to “spit” like it used to...
Before I get into an overheat issue, is this normal?

Yes
No
Maybe.

Got video?

Didn’t know I could post one. I’ll try.
Thanks

Purging air is difficult. You will need to use a short piece of hose in vertical above reservoir to force air out.

Thanks turtle, I’ll give that a shot somehow. I haven’t addressed it yet.

Purging what air?

Sorry, should have explained better. When you replace the housing it's hard to displace all the air. Even a small amount will allow cavitation and partial loss of suction which the pump will not overcome. Refill procedure is to shutoff intake seacock and fill system from above to assure complete air removal and then reopen seacock on startup.
