Hey Bordin......................sorry for the loooooong delay. I have been busy with so many projects, home stuff and family. I ran my boat again and it finally stripped out too. I went for a complete mod, no reduction drive. I had to do some cutting mods and found a way to install a Graupner 700BB 8.4v with my own homemade mounts (aluminum "L" stock, i use it for alot of things) I used a coupler off of a Cen boat and went with an Octura 630 prop. Im running it on 4s lipo (14.8v) with a Traxxas (Novak) 14.4v ESC and Novak smartstop LVC. My other rudder broke so i found this one somewhere and put it on. I just got back from running it.........runs great, motor temps about 110F . It will "jump" out of the water from a full throttle start and plane nicely, i havent checked the exact speed yet, but its more than fast enough for the little 25 year old boat. I would estimate 25-28 mph, and it handles really good, i mainly did this for my seven year old................something that can be ran up onto the bank and i wont really care. If you have any questions regarding my mods let me know and i wont take a month to get back this time.
