Have a 16 foot kingfisher bass boat, have to replace the foam and was wondering do I need to replace ALL the foam in the boat or just part of it??????

Re: Help!!!

Certainly you should replace any expanded foam that has become waterlogged or rotted. You can take a short length of plastic pipe and file 'saw teeth' into one end, then use it to core sample at various places all the way to the hull. Screw it through the foam til you hit hull, pull it out and eject the core by pushing it with a broom handle or dowel, You may find that even foam that looks good near the deck is wet near the hull.

Re: Help!!!

Hi Cindy,
Typically if it's an older boat and it has wet foam then most if not all will be wetted out. The older style foam absorb water and held it. May look good on top but usually the water is held at the bottom on the hull. That then effects stringers, bulkeads and other related structural components.
it's also a PITA to remove. Todays foams do not "absorb" and hold water. If you can determine the depth of the foam in relation to the hull. Get what is called a "Sawsall" tool. Then get the necessary wood or metal blade of depth required, shallow of an inch. Make long cuts and then width cuts, make the cuts into short squares, @ 1" to 2". The level of difficulty is in regards to the access you have. After the cuts the old foam can be dug out much easier than just ripping away at it with a hammer claw etc....You'll need alot of trash bags. the stuff seems to never end. When you down to the hull... then let's yap again.
Good Luck. This is a very common problem and your not alone. There are some very good people here with great advice! Try to post pics, make/model,year etc so we can see what your up against.

Also I wanted to note be aware of all your electrical, fuel lines etc whereas you don't cut into them as you move along.

Re: Help!!!

If you are talking flotation foam, in a boat of that age, and you are doing a total rebuild then all of it. I assume you are not talking about foam in the seats. What type of work are you doing to your boat?
