Answer
Hi Brian...thanks for selecting the undersigned to reply to your question.

When you begin to take off, make sure the engine is trimmed in toward the boat's transom, then, as you accelerate, press bow down, which will move the lower unit outward. If the boat porpoises, keep adjusting the trim until you reach a smooth and level plane.

Safe Boating
