35 fountain with extension boxes and shorties
I'm looking for some input on a 35 lightning with 7" extension boxes and 2" shorties. I'm looking to purchase, but have yet to take a test drive and I am curious as to what effects these mods will have on the boat. I am worried about difficulties getting up on plane or any other performance issues I may encounter. Some personal experience feedback will determine if I even want to go take it for a test ride. Any help would be greatly appreciated.

I have an 01 twin step with 2 inch shorties. It does not have boxes. I can get it on plane with about any 5 blade prop and I usually use a realtive small 15" diameter prop. It is not a rocket ship to plane but the mph gained makes it well worth it to me.
I would think with boxes it would even be better about getting on plane but have never tried it. Have always heard when you go back you must go up.

Not many 35's use boxes, the notch in the transom already serves the same function as a set-back box. Allows drive height to be higher. Many use -2" lowers without a box, so to optimize performance with the box -2" lowers may not be enough, may need to raise propshaft even higher.
