Best Value RTR RC Boat Brushless Upgrade, $200 total.
Purchased MG 24 RTR RC Boat NIB for less than $100 on Ebay and have about $100 in motor/esc. $200 total cost for a brushless beast not including LiPo battery.

1st runs, Proboat Miss Geico 24" RTR RC boat upgraded from 15T 2200kv brushed DC to 3,500kv Brushless. Running on Venom 2S 5A 30C LiPo. 
5 Minutes upside down after flip @ 3:15 mark.
20+ minute runs, motor and esc run cool (Brushed ran hot on LiPo).
See video for build pics, specs and details.
Needs adjusting for hop and an upgraded rudder and drive to handle the increased power and RPM. 
Likely will use the following MG 29 parts:
PRB4105 Strut and Mounts
PRB4106 Rudder
Will try 3S after strut, mounts & rudder upgrade .
