What would you think is a estimated time to get one from the underwater part cause I've been doing it for a hour now and haven't seen one so what do you think is a estimated time

So basically I need help and I wanna know if there is any way to get a Clamperl besides the sunken boat Because I did that but I was dumb and used the wrong deep sea item and evolved it into the wrong pokemon so basically i'm stuck in Hoeen forever. Also I know you can fish but I heard you need the supper rod and there is no way Ill be getting that money to be able to get it so is there any easy way to get Clamperl. Or if there is anyway to get huntail straight up with out evolving
