I have a 2003 30hp mercury sea pro twin. I have a few things done to it. The timing is advanced to 30 degrees from the stock 22 degrees. I have a few exhaust relief holes drilled at the bottom of the leg. And i think the pistons are fluted. I have 40 carbs on the motor and the intake was opened up some. It also has boysen reeds. I was just wondering if anyone knows a way i can get a few more hp. Money is not a factor. And i dont mean just go buy a different motor.
