06 maxum 1800 sr3 wet foam

[Captainfantasy]

Hi. I'm new to this forum and boating. I have owned all types of jetskis for years but this is my first boat. I bought it off a friend, he was having trouble getting it to plane. When I got it I did some research and found people talking about dropping the prop to a 14X19. When I put the new prop on it was a little better. I also saw that the hull's foam could be full of water. I pulled up 4 caps in the deck and when I pushed on the foam it was all wet. My idea was to remove all the caps covering the foam in the deck, use a plumbing snake in the holes to break it up. Then cut a hole under the seat on each side big enough to scoop/vacuum out the waterlogged foam. Once that's done re-foam it and patch it up. Has anyone here done this? Is there a better easier way? What am I about to get my self into?

If the flotation foam is waterlogged, the stringers and transom are likely rotted.
