no we're ALL confused.. lol..
YES the further back the engine gets the HIGHER it must be... not because of the angle of the transom (you are measuring height above the keel not angle) The reason the engine gets higher further back is because the boat displaces water even on plane... the water right at the transom is lower than the water in front of and behind the boat... as soon as the transom leaves a given point in the water it immediately starts to rise towards it's original level so behind the boat is uphill....
ALSO the keel will be pointing uphill toward the front so straight back (no matter the transom angle which you build around) is downhill....
sooo your engine moving downhill where the water is moving uphill requires more lift....
You do not need any huge washers or plates on the transom... the angle iron will already be spreading forces much better than the outboard brackets... you only need the same washers you would need to mount the engine directly to the transom..... under power the only forward force on the transom is at the very bottom end of the bracket or angle... the top is pulling away from the transom.....
ALSO nobody mentioned this but the bracket will not increase leverage on the transom... in fact it will lower it... the forces are at 3 points... prop shaft, bottom of bracket, and top bolts through transom..... a simple lever with the bottom of the bracket being the fulcrum
the prop is the fat kid on the teeter totter and the transom top is the skinny kid..... the bottom of the bracket is the hinge and the top bolt is you.... by moving the prop up you have moved the fat kid closer to the hinge and made it easier for the skinny kid to lift him
You don't HAVE to get it right the first time... your motor has the adjustability built in... just get your bracket close but not too high and adjust the engine up as needed for max performance
