Hi guys , just getting back into boats after 35 years . I just picked up a top speed 3 tunnel hull brand new in the box , built it with an os max 21 outboard . I followed the instructions to the letter and when it was finished I went to balance it and could not even get close to the instructions 7.5 to 8.6 balance point . I took the battery out of the radio box and placed it back towards the fuel tank and it balanced out perfectly? Should I build a small box and place the battery back by the fuel tank with a Futaba extension? Any help would be greatly appreciated, as I’m new to the hobby and at a total loss on how to approach this . Thanks Ken .
