Super Jet Blowsion Destroyers?

[Harbor]

I used a new carbide bit to drill, worked good with 110 volt drill like Yamakel stated above. Found directions yep final hole in hull is 1/2 inch

Id like to hear how you like them - what year is your ski? Like I said before I noticed when I punched it the ride was a much smoother ride as well as in the surf I felt that I could throw the ski around a lot easier ??

It's sort of a long story, the ski is a 01, d cut or long extended plate, 701, msd, 13/17, -4 poll, blowsion steering, strait bars, ada head, b-pipe, foot holds, etc. The ski is sketchy 15 mph and up, it feels like its catches water under the ski around the middle of the boat and can toss you over the side without warning, pretty unstable, no better with a long ride plate either. I put tubbies on it and it plains much better if your on your knees, if your standing it still can tosses you, still unstable. It carves way better now & holds a turn, the nose stays on top the water more too, I really like them, at slower speeds it's a lot more stable. The stability problem I think I've isolated to the intakes greats double deep design and large center rib so I bought a 201 but need to water test again, I have another even less aggressive one to try too after the 201, this is why I wanted to remove the tubbies, I had forgotten the ski was sketchy before the tubbies. My previously 96 was not sketchy, the differences I see is the intake grate

Yamakel: are yours installed in a much different position then mine? How much up are your from the bottom of the hull as measured at the bottom?
