You going to need a engine swap or a boat change I am afraid.
That 4cyl should have never been offered with that cuddy.
There are no performance parts that I have ever herd of.
Also I have herd that these 130 hp "Iron Dukes" only generate about a true 100 hp at the prop if you have power steering.
So it's 4.3 or 5.0 or another boat if you many more speed and hole shot.
