I think that I have the only diesel SH. I have not heard that anyone else has the Cummins/ASD package. My apologies if I am mistaken. I am in the process of repowering it with new Cummins QSB-480's. Should be ready to sea-trial this Spring. The water on Lake Erie is a little hard this time of year for a water test

actually crushing the 34 mold was the best thing they did. it was terrible. every one of them had to have the bottom blue printed to make them run. Bill Sirois and I fixed the first 34 built down at the Super Hawaii race shop in Sarasota. the boat porpoised so bad it would ventilate the props. after we straightened everything the boat ran great in every thing. the one 40 we had won the around Italy race with basically stock Mercury Racing 420's. that boat never missed a beat in all kinds of water for days on end.

Was the porpoising problem common with the Midnight Express 32 hull also or was this just with the SH hull, What had to be done to fix the problem?

I think the issue was with the age of the mold. they straightened and trued the bottom on them and they ran great. I think the original plan when they scrapped the mold was to make new ones but that never materialized due to some other issues with the owner of SH.

Payton (Mark) is the resident expert on these boats What he says is law

Hope all is well with you Mark

haha,Marc, I think you misspelled law, It's spelled crap.
I've been doing well this winter. But thank you. Just a little busy with getting parents to doctors.

My SH only had a slight porposing issue. Really only in flat water. However, it did had a 1/4" rocker about 4' forward of the transome. I did remove this and actually put a 1/8" step in it's place. That did move any porpusing it had, unless I over trim. It also gave me a couple more mph at top speed.
Habana Joe suggested I make a ledge where the bussel meets the transome. to free up the hull. I think I had achieved the same thing with what I did.

Do/did any Intrepids hulls share S.H. design ?

No, they were different
