    Default Setting Berkley intake on a 20.5ft Eliminator sport cruiser

    So I am doing the scary intake swap to install a ride plate and shoe. I managed to remove the old intake with out to much drama, but now comes pulling hair out time. So i picked up this intake used with a flat cut tapered shoe measuring 1/2 inch to 3/8. It was originally in a Gulwing hull if it makes a differrence. So I started marking reference points all over boat and it seems the original intake was off to one side about an 1/8 of an inch (didnt notice any previous affects, but it only went 53mph). So after a few mock ups i got it centered and set to 4 degrees and ran a straight edge on bottom of boat to see where shoe was, it was about 1/8 above the keel, is that correct? I have never ran a flat cut shoe before. Also I am going to have to remove a huge chucnk from bottom of boat for the ride plate, will probabley have to add glass afterwards. seemed a little excessive to me, but thats why i am asking. I also set the front of intake level with front of intake opening, the sides where level but the center of intake had a big hump that hung down below boat, i gound it down to match the contour of bottom, is that the correct way? I was trying to keep the intake as low as possible to minimize the cutting for the ride plate. I will try to get some pics soon. Thanks.

    Good place to start is how you are going about it. Center the intake in the keel, shoe bitting edge is about an 1/8 inch above the keel , the pump pad is 3.8 to 4.0 degrees. You have already noticed that you will have to add glass on the inside at the back of the hole for the intake and a fair amount of grinding will have to done after the intake has been set in order to for the rideplate to fit. If you look very closely a center line has been scribed into the mold so it should already have a centerline in the bottom.
