Converting to Foam core stringers and transom from original wood affect the ride?

[Hugo G K]

Wow thanks so much for replying so quickly and with such good information!

After reading the replies it made it clear that there is still a lot about my specific SC that I need to learn. Although I did leave out a lot of valuable info that I should have mentioned in the first post.
The title on the boat reads 1968 length 19 and Propul INBRD.. Since then the boat has been converted to an outboard and when I asked the seller, he claims he had bought the boat as he sold it and could not offer any additional history. I became curious so I was able to contact Carla Moesly (Daughter) and had sent her pictures of the boat. She was a little unsure herself but suggest that it could have been a bow rider converted to a CC. The deck on the boat was in bad shape so I decided to begin the restoration process and rip out the deck which is basically where I am now. The guy I have doing most of the work pointed out the condition of the stringers and suggested they needed to be filled in with foam for the core. After reading your reply Bushwacker, I did notice some stringers were hallow and if I recall correctly, there was one stringer that had wood as the core. I figured the hallow stringers probably had wood but rotted over time. As far as the transom, the wood is definitely rotting and needs to be replaced. But if you say this was normal for the stringers to be hallow then I will definitely question the work.
Tomorrow I will go to the boat and examine the stringers much more closely. In the mean time I figured I would try to put up some pictures I have just in case maybe you guys can give me some more good input on what I actually have and what you suggest I do with it.

Thanks Again,
