RedactedNarrative: operator was fishing in turtle bay near the harvey cut. At approximately11:30 a.m. operator decided to try and fish the opposite bank of turtle bay. The subject was cruising at approximately 3500 rpm's when the vessel, la 6164 ez(23 foot 1996 chris craft), impacted a submerged stump. The impact caused the motor to lift out of the water and almost break free from the motor mount. The motor is barely attached to the vessel and completely submerged. The vessel received structural damage to the transom and possible damage to the hull. Jefferson parish sheriffs deputies were able to pull the vessel to a nearby camp and tie it off to the dock. The subject did not sustain any injuries and was wearing a type iii pfd with the kill switch attached. Alcohol does not appear to be a factor in this incident.
