Wasn't this the boat that was for sale on EBAY or something, said it did over 100 mph or so?

It may have been, that is the rumor +100 but I really doubt it. I shut it down early because it handle poorly, may have been my lack of driving exp. over 70 mph, although it doesnt have hyd. steering yet! u

Post some pics, my buddy has a 1988 Scarab III with 420's and trs, runs slightly better than 60. I would think you would need a pair of 900HP motors to see 100 in that hull.

I will work on the pics.. At 4000 rpm it feels faster than my imp at WOT, My guess is Mid 80,s I get a hand held gps this weekend and find out>
