I recently purchased a 91 scarab sprint 17ft and ditched the turd 3.0l for a 5.0l ( that's what I had at the time) that I put togather it is all stock but through hull exhaust, edelbrock intake and a comp xtreme hyd roller cam. The boat goes ok but is not scary fast. What is scary is the porpoiseing I'm guessing the weight bias is totally screwed is there anything I can do to get it to act somewhat normal so I can get out the rest of the power to it. I am trying to round up enough parts to spray nitrous at it to see if i can power through it. What do you think is there any hope? I have tried props and whale tails they help trim control but that's about it I would like to add weight to the front but am not sure if That would do much for it.
