A trolling plate is put on the motor and drops down in back of the prop so it cuts down on the thrust of the motor so it slows the boat down.A hydrofoil is attached to the motor and looks like a wing.It helps plane out your boat at a slower speed.I think you have to drill holes in the motor for the hydrofoil.And I'm not sure about the trolling plate.Maybe some one who has one can help you out with that.Hope this helps.
