Had this tahiti boat for a year new had it out all last summer after i built the motor. but the last trip i had sucked some rocks (pump rebuild soon)and noticed the floor flexing and water leaking from the transom .. Pro-balsa is marine grade balsa enhanced with polyester resin and epoxy. great for boats, planes, models and other projects where a light core is needed.. Jet boats; need some help with redoing my floor! wood recommendations? page 1 of 2 1 2 last. in a lot of these boats the floor is part of the structure of the boat. if you do not glass it back in you may affect the structural integrity of the boat. is when you have a piece of balsa wood cut to fiit the area between the stringers, glass.
This boat had a balsa floor sandwiched between fiberglass. i had to scoop it out and was wanted to go back with foam since it has none! also planning liquid foam on the underside of the top half. the balsa pieces were 3/4" so i am thinking 3/4" dow foam followed by some urethane liquid foam for the gaps.. Boats for sale we have found 206 1/4″ balsa on floor only. 1/4
