Wow, samich..............................what is that 24pinion and 32 spur............i've always wanted to stick my monster system in a boat (its in my 3905 now) But OMG.............................i think the min voltage for the monster sytem is 14.4v, you might want to check it..................you may need to go 4s, but gear down, have some mercy, BTW i am predicting that you will shred, destroy, liquify your u-drive on the first run, but i hope not. Keep us posted, i would love to see a vid.

P.S. - castle states that the monster 2200kv on 6s is equivalent to about 6 h.p. !!!!!!
