So here is what is going on, I'm in the process of completely restoring this boat, it's make is a 24.5 foot saber edition with a outboard motor. To this point l have completely rebuilt the transom, tore all the floor boards out, and removed all of the water logged float ion foam. After the foam was removed found some minor pitting in the hull, not to bad no holes thru the hull. I then sand blasted the whole bottom of the inside of the hull, then sprayed inter protect 2000e inside the whole hull. What I would like to now is if the flotation foam needs to be replaced in the hull. I contacted this company out of San Diego called aero marine, she informed me that they sell a 100% closed cell foam product at 2% density, I bought a 2.5 gallon kit for 245.00$, has anybody gone thru this process.
