Tsunami I.O engine repower question

[bigeasy1]

Thanks abl1111,I'll be using this boat strictly for great lakes(lake Ontario)fishing,salmon trolling,so it will never see salt water.
I presently keep my current boat on a trailer at the lake and only keep it in the water for a week at a time when i make a trip about one a month.I will be doing the same with the seacraft,until i move up that way a few years from now,at which point i will keep it in all season.
What do you get for speed with your 5.7 ?,and is the Bravo three a lot better in manuverability in docking than the Bravo 2?
Thanks
John R.
