Cant help you on the questions, but a friend of mine just bought a new 42 tiger also. He got it home friday I belive, and All I can say is wow! He's just getting his first seat time in it and taking it one step at a time. I dont know the prop he's running or anything, it has corba power, but I'm not sure what HP, it does have bravo's, but I dont know which one's or the props he has. Sorry for all the useless babble, but the boats too new and everyone was checking it out all weekend, so I didn't have a chance to get all the details from him cuz he was busy showing it to everyone. I was partying elsewhere, and did the quick tour and got back to the fun, but I'll keep an eye on this thread and maybee your tests will help him once he gets comfortable with the boat. I must say I think its one of the nicest boats I've ever seen.
