[spareparts]

just thought of a couple of cheaper and easier things to try, get someone to take a picture or video of your boat running at speed, take a look at how wet you're hull is( how much is in the water), check the angle of the t-top( is it acting like a parachute?). Sometimes a picture will save a lot of steps or open your eyes to something that you never thought of. Second thing, have you thought about putting a manual jackplate on it, shop around, you can probably pick up a used one for $100, they make it easy to set the engine height, its not as sweet as the hydraulic ones, but it still helps, it should bring the bow up a little as well, depending on the setback. You could really fine tune the setup, a jackplate is cheaper than another prop.

BTW, what kind of skiff do you run?
