Desperately need help please 97 Volvo penta 3.0 flooded from blown hose, now, turns over for a few seconds then no power

[Mainefirstinboard]

I shut the boat off to drift, didn’t notice if over heated but went to start and nothing, opened the back and noticed water filling the bilge up to oil pan, not sure how much higher it would have gone. Let it sit overnight, turned it over real quick and it had power, replaced the hose the next day and it cranked for a little bit, like 30 seconds then just stopped no power, bilge was still working the first time. When I tried the second d time after replacing the hose I saw a little smoke coming from around the alternator side. Not sure what I’ve done, any help would be greatly appreciated, thank you very much.
