Yamaha F25 EFI Intake Modification for more power

I have a Yamaha F25 25hp 4 stroke outboard that has been low on power since I installed it on my boat. I found out that there is a simple fix to get the max power output. The factory air inlet is very restrictive and chokes the motor for air. Watch to see what I did to improve the performance of the outboard.
