I can put my 17 foot v bottom tracker in at Kennedy no problem. I normally put in at the north ramp and work south from there. And I hear you on the props. That lake has cost me two in 3 years plus about 4 repairs at $60 a shot. I've got an old junker I save just for that lake lol.
Briggs woods has been pretty lack luster for us the last couple of years ice fishing. Never messed with it open water so I don't know what its been doing. Send me a pm with your number I'll be glad to chew the fat anytime.
