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.
