Upside of this solution is I don't need to fix or replace alternator. Also would have benefit of keeping generator starting battery topped off via shore power
when plugged in so it's always charged.
Anyone have any comments or see an issue I could be missing?

Our Panda 10kw generator had both the alternator and water
pump replaced with external sources. (i.e., no belt...)
The alternator is just an idler pulley in case a belt driven water
pump is of interest in the future.
There is no need on this boat for a generator alternator as when there is AC available [or the main engine
is running, it is sunny or windy...] all batteries are being charged.
Why no water pump either?
When the manufacturer had a batch of bad impellers years ago- but didn't admit it until 6 months later- the previous owner bypassed the built-in water pump replacing its function with a spare 110VAC March pump [used for the raw water coolant
loops for the air conditioning
systems. [10 impeller changes in 2 months would make me re-engineer that system too...]
He also relocated the heat exchanger
to outside the generator's acoustic housing so it could be replaced with a larger exchanger [and is more readily serviced... They were in the tropics at the time...]
These changes make everything much more serviceable and provide redundancy if one wanted to put a belt back on to run the built-in water pump [with a functional impeller...]
We don't hesitate to properly [and cautiously] re-engineer [optimize] systems using standard components, methods, and procedures, but only when necessary... [Who needs to make more work on a boat?]
