Re: Larger boat, why?
ok, Obviously I love Crownlines but you would be hard pressed to get a Crownie to 70, my 248 has a 7.4L MPI but it also has a Bravo III so it will suffer on top, if I had a single prop Bravo I could get 60 out of it easily, 496 Mag and were a pretty solid 65.
Baja has some nice Bowriders that will go that fast properly setup but they lack the refinements of a Crownline or Cobalt, but you have to make that decision on your own, Advantage is a nice product and I hear great things on the speed side probably better then 70, Nordics and Powerquest are also nice boats but are clearly go fast boats that your going to have to decide if you want more speed or more luxury, I'm fine where I am at but like you I feel that go fast need, I will eventually go for a 502 or 496 MAG and that will be the end, I love my Bravo III and what it gives me, the bottom end bite I want, I will be plenty happy at 60 MPH. Keep in mind that going that fast probably means going longer, even a 26' boat is likely to be a little "fun" at 70!
I am sure I am forgetting a couple, I have friends with all the makes I mentioned and they love them all. I hope this helps.
