I had one for 8 years, could never get it to run right. Had 200's on it though.
Sold it for 3K lesss than I paid last year.
I would suggest a seatrial before you buy.
Everything else you stated can be added easily.
Where did they put the generator?
My cousin has that same boat with a bracket and full transom. We fish 4-6 guys with a full livewell and no problem with wet feet, not water on deck at all.
You best bet is a bulkhead like you are talking about, also less fuel. You very rarely need to tote around 150 gallons while fishing inshore.
