How high did you get the motor without modifying the transom? Before you go crazy on getting it higher you might put a set of fins on the lower unit and see what it does to the porpoising.
There has been some discussion of porpoising so here is the story.
When Capeman and I took it out for a rat run she would porpoise bad anything over 30. I tried moving my 240 lbs to the bow and it dang near tossed me out

Engine was clearly buried and would only reach 4300 rpm.
I raised the motor all I could, 4 holes, and tried it again. This time the av plate was still buried but was able to reach 4800 rpm and 35 before the porpoising got out of hand. So now I have taken the Bob's jack plate off of my dory and put it on the sintes. With the jack plate I will be able to raise it more than enough. I think I will start way too high and work my way down as needed.
I knew from the start when I built the bracket it might be a problem and was willing to take the risk. I have not and will not ask JM for his advise as he wants nothing to do with homemade brackets and for very good reasons. Early on I said if it does not work I would cut it off and make it a standard transom and that is what I will do if I can not get her lined out. A fin and trim tabs will be tried before I go the saw route
