Octane Re-Foam Materials Revisited..Constructive input please

-I am in the process of De-foaming whats left in my Octane hull, I know these Wammer/Polaris Hulls leak in water like Swiss cheese. However, I am going to need to put something back into the Hull Tray. It is going to be damn near impossible to seal up all the leaks, Knowing water will make its way back in... I need something that will not absorb the water. I plan on still running my drain plugs as well.

-I have heard of many options based on search after search. I know there are cheap alternatives compared to the mail order materials that come in 2 part pouring process.

I wanted some insight as to what is best for my application. Hopefully this thread can dial in someones decision making process a little easier.

The most common ways I have Seen or Read About are the following:

-The 2 part Poured Foam Method-Often the most expensive in material cost.

-The "Plastic" 38mm Ping Pong Ball Dry Fill, As well as the Ping Pong Ball Reinforced with 2 part Foam -Can be Expensive due to cost of Ping Pong Balls and Foam

-The Extruded Poly-Styrene Board ( Green or Pink ) available at Lowe's and Home Depot- Cheaper and Readily available -Cut to shape and Stuff In Place
: A note about the Poly Board-Must be Closed Cell material which will not absorb water-White Styrofoam is a waste as it will breakdown and absorb water.

-The "Great Stuff" Spray Can Foam Method-Not Advised as it is said that it will not dry completely and will still absorb water-Also costly if using a lot of cans.

-The Plastic Soda Bottle Method- The Cheapest I seen Yet, Still effective

-The Pneumatic Rubber Inner tube Method- Don't have much to describe other than that, I really haven't seen it done.

* I have not worked with 2 part foam and don't really know how much I would need, I don't have an issue using the foam as it seems it would be less time consuming after I re-glass my tray back together, and CAP or SEAL off my pump inserts and around the exhaust tube etc. But So far I have not seen anyone use my idea that I have been tossing around, I have heard that kayak makers use them...

-I am thinking about cutting up and packing a bunch of FOAM POOL NOODLES inside and closing it back up. They Don't absorb water that I know of and are pliable to fit curves and compress into the gunnels. Plus they should still allow for any water to still make its way down to the drains at the bottom most point of the rear Hull extensions. Please Advise If anyone has tried this method and has had a positive or negative experience. I really don't want to cut this thing back up in a year or 2. Thanks -JW
 
fwiw i did pink poly steyrene blocks then the 2 part for the foot holds. i honestly think doing the whole thing is two part would be uneccasary.
great stuff- wouldnt even think about doing it.
plastic soda bottles- sure its cheap but a board of polysteyrene is cheap also.
i remember reading somewhere that the pool noodles with break down over time?
that being said, id use the polysteyrene. and reinforce that area with some biax mat while you have it open

I Read the foam thread, Great documentation. I think the poly styrene is so far the ideal set up. I have not gave up on the noodle idea entirely...I still think it would suffice, But not sure it would have as much floation mass as the styrene boards. They are rigid and a much more dense material. I liked the idea of the noodles in the fact that they will compress and bend to any shape. but the rigidity would suffer under the tray to an extent. I do want to reinforce the inside of the tray while in there. I have not heard ot read of the pool noodles actually absorbing water, but it may be possible..

-How do I cap off or seal my pump inserts? I want them to keep water out of the tray ( big issue on the octanes) but i dont think slopping epoxy overtop is helping the hardware rethread back into the insert...secondly, If there is a way to keep them from future spinning when removing the pump bolts. I have heard this has happened many of times and guys have to cut into their trays to repair. What do you guys think?

Do the pump inserts have a hex head like an SJ?

I believe the pool noodles will absorb some water. I want do do ping pong balls but only cause its kinda funny. I think the home insulation is the way to go, with 2 part as filler.

Yes, and they are not capped off. they are notorious for leaking even though they were "sealed with green glue at construction"
