2001 hpdi 150 on 1976 sf 20'

Wondering if anyone has this motor on their 20ft potter hull that hasn't raised the floor. Very interested in a motor but concerned about the 475lb bohemith on the back. I will be rebuilding the transom to raise to 25 with coosa this winter so strength is not the issue. I 100% understand that these boats were made for lighter motors but I have also seen many 200 hp motors hanging on the back of them too so it can't be all that bad. I rarely take trips out in the ocean and if the boat is loaded with people they are sitting in the front anyway.
