On July 3rd I dropped my boat in the water after buying it and servicing it . It was docked and drove it a few times with no issues. On July 10th I went to take it for a spin and the motor and the bottom was full of water. Thankfully my neighbor had a pump and pulled to get it out of the water . I’m so confused in 1 day it just filled up with water .. any ideas before i bring it for service ?
