i too can blow out the prop when trying to get on plane...but have worked thru that part....what should i do when im at cruising speed(3500 rpms) and i have it trimmed up a little to keep the boat flat...then i start to ease into the throttle and the engine winds up but the boat doesnt accelerate...maybe it is something i am doing wrong...i have even tried to drop the drive when cruising before going WOT then start trimming up slowly and it still does the same thing....I am open to any and all suggestion..
