Willy,
I would question just how much the situation you describe*will improve with a heavier engine. *The stern might sit 2" lower with the 150 when the boat is "at rest" .... *but that is not the critical time for you. *You need the engine 2" lower *... *when the boat is "up on plane". *When on plane, the height of the cavitation plate - relative to the keel and to the water level flowing by - *might not be all that different for the 115 vs 150. *At least ... *that is how I see it. *I am interested in knowing how you make out - *good luck.
