Gen III? From all research I did on 35-42 fountains the last hull iteration was 2004. That was the last year the 42 was modified. Engine configuration doesn't change the bottom. Hell the mid to late 90s 42s were available side by side, stagger or trips. I think once the 38 got the larger steps in 02 or whenever it stayed that way through production. Same with the 35. Once it was a twin step it didn't change. Same with the single step. R3 told me the single step 35 was same bottom for all of its production. Just the X changed

ICU,
Gen III is what i read somewhere, just trying to educated myself on 38's Thanks for your input

Gen III does make since if straight hulls were I, small step II and the large step III.

I put Stellings extension boxes on a 2003 38 semi-stagger and was happy with results. After getting it dialed is with
props and spacers the boat ran 98 with bone stock engines. The boat also had -2 Merc shorties on it. The boat handled great and got on plane like any boat with a high x dimension. It ran great with 4,5, or 6 blade props. The boat ran 94 at the Shootout and always won its class. As far as I know the hulls are all the same from 02 on.

ARB38,
Thanks for the info, was that with 525's? And your final configuration was Stelling boxes with -2 Merc shorties and what size spacers?
Thanks,
Dean

The boat did have 525’s. The original set up was to have the prop shafts 1 1/4 inches above the bottom of the boat. That was to high. I ended up with a 1/2 spacer which put the prop shafts at 3/4 inch above the bottom and that was the best setup. The boat was great and really surprised a lot of people how good it was to just have 525’s.

ARB,
Sounds like you really had her dialed in! Do you happen to have pictures of your final set-up?
Once again, thanks for all your knowledge!
Dean

Dean, sorry but I do not have any pictures of when I put on the extension boxes. Is a little bit of a project to put them on and get the boat dialed in. The boat was good without them so most people would not care about the gains from the boxes. It ran 91 without the boxes so not to bad. The newer boats with ITS should be pretty close with a little dialing in with props.

Here it is Al.

ARB,
Thanks for all the info.
