Boat Lift Placement

It is a Craftlander. It is made by Nucraft and they called their lifts Nucraft until 2000.
I want to make sure I get enough height between the front and rear beams, the prop and the fins. Water is only about 3 foot deep at the front of the boat, about 4-5' in the back.
I can dig the sand deeper now if I have to. Have teenagers and the "Boss" driving the boat so I want it to be fool proof. It should be much more relaxing not to have to pull the boat out after a day of fun. Roads get pretty wild leaving the Lake, even not pulling a boat.

I don;t have a 2001, but I copied my trailer bunk dimensions and welded them to W6 by 15# Wide Flange beams.

Look at the trailer bunk mounting distances on either side of the engine to get a feel for the proper spacing. I made mine a little farther apart since you want to be able to stand on the bow or stern without any tipping!

I ran my bunks flat just like on the trailer. Standing the 2" by 6" on edge is risky and more force on the hull. On edge, the bunk won't flex as much and conform to the boats hull.
