RedactedNarrative: Units 1 & 2 were traveling southbound on the ICW. Unit 2 hit the wake of another large boat and threw off both of the riders and launched it into the left side of the transom and engine of unit 1 damaging the coping, railing, and cowling it . The spark plug probably damaged since the engine would not idle properly afterwards. Unit 2  damage on the left side of the bow rub ail and cracked hull.
