welcome to iboats.
i would try refilling and bleeding. raise the motor all the way up, pushing up button and physical force. lock motor in place, fill tank. close tank, now lower all the way down, now back up same way, refill, close lower. repeat, repeat, repeat until it will take no more fluid. it should work now. cycle 6 times, check fluid. if still full. you are good to go. watch for leaks.
turkey baster ear syringe help fill.
