Wet End Replacement

[CuckooChris]

Need help @RDspaguy. Friend of the family asked me to take a look at their leaky hot tub. I thought I got lucky and found a pinched o ring on one of the wet end connections. I replaced it but it's still dripping from what looks like the seam in the wet end. Problem is, I don's see any way for it to come apart. I'd like to replace it, but I'm confused how to even do it. Here are some pics of it. Appreciate any help, thanks. Chris

I have only seen those in jetted baths and washing machines. The wet end is a sealed unit, thru-bolted to the motor, likely with a D shaped shaft end, no threads, that slips into the impeller. Remove the thru-bolts and it should just pull off the shaft. Replace the whole thing.
From a quick search it appears to be no longer available in 3/4hp. Going to need a new pump/motor assembly.
