Check this website out:  http://www.hobbycity.com/hobbycity/s...=&sortlist=   I've owned a few of these motors and they are awesome.  The best thing about them is the price. Read the reviews on the site and see for yourself.  They also sell ESC's and other accessories but I usually spend the extra money in the ESC dept.  If you look at the top of this speed electric forum there is a guide on building BL electric setups.  I've found the information invaluable.  I'm currently building a FE 40" V-hull that had a .65 OS Max vr-m in it.  After many head aches with nitro marine engines, I now only have Nitro aero engines for my airboats and FE boats.  For Power go LiPo, check ebay,  yes ebay!  I bought several Lipo's of good quality on ebay.  For my BJ 26 BL I bought 2 7.4v 25c burst 35c 4000mah 2s1p LiPo packs for $56 for the both of them!!!  I've run over 10 charge / discharge cycles through them with no problems.  Using my Big boat as a chase boat, the big boat's speed-o-meter said between 40 and 45 mph, dead center, so I estimate 43mph.  Also for an old Cen Baja that I put a 775 in with brushed ESC and LiPo BL voltage cutoff device; I got a 14.8v 35c burst 40c 3000mah 4s1p LiPo pack for $60, again on ebay!!!  So far I've run it through about 5 cycles with no trouble  (sorry no speed data on this one as it hasn't been on a "fishing" trip with me yet ).  Contrary to popular belief you don't have to spend a fortune to get good quality hobby grade R/C stuff.  You just have to do good web searches and make sure you are dealing with reputable websites.
