RedactedNarrative: Just purchased the boat and put the boat in the water for 5 minutes.  Started engine and put it in drive, nothing happened.  Turned boat around manually then started again.  An explosion started in the engine area and there was a huge fire.  Other boaters on the water started yelling to get out because it was going to explode again.  Flames were getting larger, couldn't get fire extinguisher.  Couldn't get off the boat from the back, so jumped on the dock.  Flames were so large that we had to jump from the dock into the water so that we wouldn't get burned.  Called 911 immediately and officers were on site within a few minutes.
