Does anyone know if the poly gas tank on a 215 explorer is "foamed" in?  also, If water spills over the top and down the sides of the tank, would it just drain into the bilge?

Next question do I need to use 1 inch nidacore or would 3/4inch be sufficient ?

I used a similar product (Plascore) for my floor and had to make significant improvements to the material everywhere I mounted something. I knew exactly where my stringers were, how wide and how thick I made them. I planned my seat design to land in the center of the stringers and I was able to drill and embed threaded inserts


into the stringers where they aligned with the holes in the legs of the seat. I over-drilled the plascore and filled the holes with thickened resin. Here is a pic of the seat test fit.


The final install I removed the threaded rod and used countersunk bolts (1/4"-20)


For a tower of any type except the ones that mount to the console, I personally would bed some oversized 1/4" aluminum into the stringer and drill and tap it for bolts. Then lay the floor and set the tower.

So I’m to the point ready to put the floor in my
Boat and based on the cost I’m going to go with nidacore. My question is is nida core strang enough to hold a half tower ? My plan is get some aluminum angle made and attach them to the stringers so I can bolt the tower to that through the deck. Using 1inch nida core for the floor and just worried about flex as well. Any suggestions would be appreciated.

I am looking to get a cockpit and bow cover for my 2004 Osprey 215 sport, outboard, dual console, no factory ski pole. Does anyone have an OEM cover with the Ameritec tag showing the part number and date of manufacture that they could snap a picture of and send me? RNR-Marine can supply if I have that information.
Thank you!
