There are many factors that can cause a boat to have difficulty coming onto plane. Consider for example, your total boat weight, weight distribution, engine trim, hydrofoil, and transom tabs before investing in a new propeller. To assist in the correction of on plane problems, you may also need a different propeller. Your first choice should be a propeller with more blade area. Keep the pitch the same, but provide more blade area either through a slightly larger diameter or an extra blade. In cases where this would not be enough, you may have to trade some top speed for a better bottom end through reducing the pitch a couple of inches.
