I purchased a 84 Hydra Sport 2400cc about a year ago. I have slowly been making repairs and upgrades to the boat. I can not find any information on this boat such as hull construction or layout. I am looking for someone who may have done a rebuild on one of these or has seen the construction under the deck. The boat leans to the left under power so I think there might be water located somewhere but I have not been able to find any. I have cut two access ports to see what is under the deck. All I seem to find is dry foam everywhere. I am beginning to think the boat is foam with fiberglass overlay. I also removed the 100 gallon or more gas tank to see what I could find but turned up nothing. Any information on this boat will be greatly appreciated.
