    What you have drawn in typically what is done, and is preferable to what I illustrated, imo, But the problem that you have, is the engine has to go up, and that could present difficulties, as you will run out of bracket holes.

    What do you base that on, was the propellor losing grip ?

    yea it did,but when i look from behind outboard the cavitation plate is litlle bit higher than bottom of the bracket,if cut in hull line it would be on spot

    It does not look high to me, the cavitation plate is the one immediately below that zinc anode. That is just a splash plate above it. It may not be the end of the world if your motor ends up a touch low, but it is not ideal.

    i will do like you draw mr,efficiency,but how should i line cavitation plate,looking at hull or what,i do understand the sea rises after it leave the hull,would it be better if i just make sure the pod is straight with hull,or just extend a hole area around bracket,the guy is coming tomorrow and i still dont know what i should do

    Don't be panicked into a rush job, you may get something that renders the boat unusable. My initial thought was just get rid of the "hook" in the bracket, and have the bottom of the pod, on the same line as the hull proper. You will then have to raise the engine a few holes on the bracket. Anything more radical than that, you will run out of room to raise the engine. With the sand out, and the hook gone, you must get a substantial improvement in trim angle, and you still have engine trim to fine-tune.

    That looks a lot better. You want the cav plate an inch above the bottom for every 6 inchs away from the transom as a rough guide.

    I doubt he has near enough room to lift that motor, though, which was the concern I emphasised earlier.
